Summary: While in theory we should never delete views before removing them from the hierarchy, there are some exceptions: (1) Some mysterious cases that don't seem like bugs, but where the child still seems to keep a reference to the parent: (2) When deleting views as part of stopSurface. On #1: in the past we had issues when we assumed that ViewManager.getChildCount() would return an accurate count. Sometimes it's just... wrong. Here, I've found at least one case where a View still has a parent after it's removed from the View hierarchy. I assume this is undocumented Android behavior or an Android bug, but either way, there's nothing I can do about it. On #2: there are valid cases where we want to delete a View without explicitly removing it from the View hierarchy (it will eventually be removed from the hierarchy when the Root view is unmounted, but it may still be "in" a View hierarchy when it's deleted).
