Besides upgrading Crawler (still disputed) and the Khepri change (I'll get there), it should be fine to apply this stuff.
As for Khepri, I'll paraphrase from elsewhere.
It seems impossible for her to not be controlling brains to some extent, given that all the powers manifest from a part in the brain that's the connection to a shard, and that she uses Thinker and Tinker powers. There's also the matter that it's more a removal of restrictions on her original power, which let her perceive through her bugs (meaning she's affecting their brains since that's how perception works). There's also the matter of the role of her shard.
Tinker powers work with the Shard supplying the user with knowledge of alien technologies and an innate aptitude to this tech. It also messes with their minds to force tinkers into a specialty, like how Leet's inventions are sabatoged by his passanger if they're too similar or how Kid Win's shard is probably why he has ADHD. Tinker powers are pretty inextricably linked to the brain, and she forced all the tinkers to work together which would violate a few of their specialties. It seems kinda impossible for this to not be affecting the brain.
There's also how she uses a multitude of thinker powers, but the one that most readily jumps to mind is that of
The Number Ma. His power is vastly superhuman perception and thinking. He perceives and preforms very complex math without a second thought, letting him "see the numbers behind everything" which Taylor uses to coordinate strikes. Perception and thinking are also both very connected to the brain, and she's pretty clearly got control over his usage of those.
It is also important to consider the purpose of the Queen Administrator shard here, and how that shard affects minds just fine. It destroys Taylor's when unchained, for one, and even takes her over enough to speak through Taylor according to Contessa. Speech is, again, very much centralized in the brain. The fact that Taylor lost her ability to comprehend such things as body language, speech, written language, and eventually being able to see things as anything but conflict is also clear examples of QA playing havoc with minds, though tbf it is on the user. Taylor's not the only example of this though. The Administrator shards in general have the purpose of coordinating and manipulating the actions taken by other lifeforms. Her dad's hypothetical powers follow this, Aidan's power follows this, and most importantly, the Admin shard's true purpose to Entities fits this. It's supposed to coordinate the absurdly massive number of shards that make up entities into one cohesive unit and arrange their configurations, which fits right in with her control over massive numbers of bugs and eventually people. Glaistig Uaine, who can see shards and who for whatever reason knows how the Cycle works, refers to her shard as extremely important and integral to the entities, further supporting it acting as this brain of the entity, almost. There's also how Scion released a few admin shards when dying, which also puts it as one of the integral shards that it's necessary to retain a few enough of for the entity's avatar to function. Now, let's remember that the shards have their own distinct personalities and all that, but yet can be subsumed by a shard that has a green name on it. Seems fairly mind manipish.
I think the best explanation for this is in how Khepri's power explicitly grants a far less fine degree of control when compared to before Amy ****** with Taylor's head, and this is why she can't get full control and stabilize people's emotions. She's not like Cherish, Heartbreaker, Goddess, Canary, etc and emotions do seem off limits to her given that Moord Nag got so stressed out that she had a stroke (where Taylor otherwise could just make her not do that), but she can pretty clearly mess with heads in some ways. I see it as you maintaining your consciousness but essentially being a prisoner of your own mind and body, as she ultimately has control over them but it's too crude a control to extend to things like emotions and all.
