Decent list, but no we need to change the "Bonus actions" that are supposed to be actions. It's a game balance issue, and it affects so many things.
Rogues are nerfed because of it.
Shield Master Feat is nerfed because of it.
Goblins are nerfed because of it (They have disengage as a bonus action)
Melee characters/monsters are nerfed because of this. (Less opportunity attacks)

I agree with much of the lest, but no, these things needs to be changed back. Especially if they are going to keep high ground and back attack advantages, because free disengage makes getting those advantages so much easier to do.
