I don't think it's a 'technical restriction' at all.  Your onCreate()
method might have drawn itself differently, depending on the screen
orientation.  Just because you have no use for this doesn't mean that no
one else would.

Just use onSaveInstanceState to persist your app state, then restore it
in onCreate.  If you do this, users will be able to leave your app
entirely, and come back to it without interruption.
