Completely agree with infinite removal, and theres a multitude of other showings like Shadow you can bring up as well.
Since we are already on the topic of major removals, why don't we discuss the
night palace feat? It comes from a prima guide that in almost certain does not meet the
new canon standards based on approval, as its just a guide
written by a random from the UK, with no real input from the actual devs/writers of the game themselves and evidentially so. It even gets major plot recap details wrong such as claiming Darkspine Sonic has
4 of the world Rings despite
only having 3. It even gets the forms
name wrong calling him "Darkspines" instead of just Darkspine.
Now regarding the claim of it being infinite,
this is the corridor that supposedly "turns into an infinite space",
not only is it just spatially expanding to where you can still literally see the exit, it only extended and is blocked by 3 gates that Sonic uses the Astral Plane to fix (shown in more extensive gameplay). I'm more included to believe it is a hyperbole rather then completely literal just to enhance the effect of the spatially extending corridor. Even if this were to be taken literally if the statement was completely reliable, it'll be more like infinitely expanding rather then an innately infinite space based in its portrayal in game. However I don't think the claim that its infinite is reliable at all based on what's shown in game along with the source of the statement itself, an unreliable prima guide that doesn't meet canon approval standards. I've even completely looked at a much more reliable Japanese Secret Rings Guide published by Shogakukan:
Sonic to Himitsu no Ring Saikyou Kouryaku Guide, and I did not find any statement suggesting the same infinite size that the prima guide does. Therefore, this feat should be removed entirely.
