Yes, that's the whole point of the new lifecycle-aware components, no need to unsubscribe/remove observers.

Cool! Thanks :D

Can you please update the docs about it?
As a precaution, I always remove the observer when not needed (even asked about it here), even if I use it just for onDestroy event.
It's especially true for ON_DESTROY , that we don't need to call removeObserver for it, so maybe add a note there:

https://developer.android.com/reference/android/arch/lifecycle/Lifecycle.Event#ON_DESTROY

?

In the event that onDestroy which is not guaranteed to be called, is not called, does the observer ever get removed?
