Hell, even if Otherworld had arguments to be 1-A, there are enough anti-feats of it. From the top of my head:
- Wishing Dragons like Shenron being capable of affecting souls resident on the Otherworld (they need to do so to revive people).
- Goku teleporting on Cell Saga to Kaio-Sama planet with Cell, meaning he locked Ki of Kaio-Sama from the living world (anti-feat of qualitative superiority. 1-A energy cannot divide itself to be part of the lower world), accessed it without 1-A help, and Cell's explosion –a being who is below 1-A– caused significant damage and killed (supposed) 1-A beings.
- All instances of the Genkidama where otherworld people participated, like in the Buu saga. If they were 1-A, their energy wouldn't be able to flow through a lower world, and would've destroyed non-1-A beings like Buu
- The Otherworld being contained in a timeline which is affected by time travel from non-1-A beings like Trunks
- Frieza refused to repent in a Soul form, so Yenma needed to trap him in a hell instead of following the average reincarnation.
What do you mean "if had"? I already showed some and you didn't even argued most of them. Heck, you didn't say a thing even about the one I base qualitive superiority on
First: Shenron can't actually manipulate souls, as he wasn't able to do so in Fusion Reborn movie, saying that Enma controls them
Second: Again... I already address that and you didn't say a thing about it
[Some might ask, how people from other world can enter Afterlife and leave it? The answer is in Daizenshu and Chozenshu.
Afterlife can be visited
by dead people and those
who has permission from the Afterlife. But even if you don't has permission and enter the Afterlife via Shunkan Ido or Kai Kai, you still bypass the barrier, which makes your existence simillar to soul(the same thing probably happens with those who has permission) as it's shown here:

Translation:
Title: THE WORLD AFTER DEATH (Scheme 3)
This world (The World of the Living - the lower part)
All living beings:The lower circle on the scheme.
Process: When a living being dies, it becomes a soul and goes to the World of Enma, which is located in the Otherworld.
Transition:An upward arrow with the text "Become souls."
Judgment in the Palace (Center)
As it shows how by traveling in the Afterlife and bypassing the barrier(wave thing) the person's existence becomes like soul's, as it comes from the Mortal world, which is shown flat(2D), to Afterlife, which is shown as 3D objects in contrast to Mortal World]
Third:It happened only in Buu saga and Buu was stated in several guides being able to destroy the Universe and stronger than highest gods, so it's kinda weird to think he would be weaker than average Afterlife beings. And ki from Afterlife flew from the Afterlife to Kaioshin realm, which is even more durable than it and comparable to it in size, so yeah...also about ki flowing from Afterlife see the second and this
"Furthermore, since the "lack of continuity" that exists between the higher level and the lower one is structural, and not causal, there can potentially be more unorthodox ways of bypassing the 1-A barrier. For example: Things that don't have anything to do with raw power, but just a general transfer/exposure of information between one level and another. Another example could be cosmologies where a higher level originates from the thoughts/beliefs/etc of inhabitants of a lower level; while these thoughts literally originating within the lower reality and then somehow "floating away" to form a higher one would be a disqualifier, no anti-feat is present if the verse has it so these operations simply already exist in a higher reality."
Forth:Timeline contains WoV which is already timeless and spaceless world and timeline changes affect it too, so time travel(they travel in timeline all the time) changes timeline and everything in it
FIfth:That's not how it was. In DBS hell people need to say they are sorry for their sins, so they can live in hell peacefully, but Frieza is a die hard
And that's without even entering with the obviously wrong statements like Time not existing in the otherworld (which was discussed before several times. Most obvious arguments being Whis' Time Rewind reviving people from Earth, for which he'd need to affect the Otherworld, or the endless times where characters needed to hurry because they have little time to train before a villain arrives), or objects in the otherworld being non-physical when we have literal planets with gravity, Goku was gifted a physical body to be there, the snake way having length, Kaio-Sama giving Goku 40kg weights to train, etc.
Whis could revind timeline, not just time. We can downgrade the same way that Aftelife and Mortal world are two separate space-times, because Whis revinding time didn't revind timeline but only time, meaning there is only one space-time for them.

About time moment...we already discuss this about WoV several moments ago, didn't we? And in Daizenshu 6 it was stated that alive Goku attained physical body, meaning he didn't had one before(in blog)
Encompassing an infinite realm to the point it cannot be seen is not enough for a (N+1)-D, let alone 1-A.I
I wasn't trying to scale it by that...
And well, let's better not start talking about how "the afterlife wasn't affected" is wrong because of the several statements of the entire U7 being at stake, how it'd be reduced to empty nothingness and no one would survive, how the same shockwaves didn't destroy the Kai realm despite it being outside of the macrocosm and travelling said infinite distance instantly. Or how a shockwave travelling "infinite" (it isn't really infinite, but whatever) distance growing stronger the more it travels isn't enough for it to reach a High 1-B+ AP, which is what your blog is implying.
Shockwaves with each punch was getting stronger. If you look close, from the first punch nothing was destroyed, after the second one planets in mortal world was destroyed and after the third one everything would be destroyed, which is stated by Kaioshin. The shockwave didn't do a thing to a Kaioshin realm. It traveled infinite distance only in the mortal world and we don't know the real distance between Afterlife and Mortal world, when the main was to show that even multipliting by itself won't let reach the Afterlife.
Hell, if Otherworld wasn't affected by Goku and Beerus shockwaves you'd end up downgrading BoG from 3 to 2 universes instead
How and why? And you already tried to downgrade macrocosmos just to Low 2-C, seriously?
