We had to add a way to disable animations in the BottomSheetBehavior class since it doesn’t use any of the animation frameworks (so the animations are not disabled automatically).

Hmm, is it (although very unlikely) possible, that it was the first time someone at Google actually tested something with this class and realised 'disable animations' option is missing?
