We still live in a world where every game does not ship with 100% rebindable controls and game devs think they know better. If a game has too many functions to make rebinding an option then you simplify the inputs rather than removing it as a player option.

Hardware-level rebinds don't count. I cannot be expected as a player to create dozens of profiles for every game I play, memorising the in-game functions as I go. Also some buttons cannot be changed, for example on the Xbox OS you cannot map face buttons to the triggers. And if the game wasn't designed with rebinds in mind then it can cause all sorts of chaos.

Platform holders should make this a requirement for software licencing, simple as that.
