My current plan once attach/detach is deprecated is to instead use add/remove and use SavedState with ViewModels so that even if the fragments and their ViewModels are destroyed, I have some state to restore afterwards.
This means that each fragment's viewmodels stay alive because the fragments aren't destroyed. The active fragment is swapped when the user selects a bottom navigation destination by detaching the current fragment and then attaching the target fragment. I'm using attach/detach to maintain the state of of a few fragments that is displayed one at a time. Just trying to start some constructive discussion here.
