The onBackRequested trick didn't work on the top level page. Which seems
odd to me - why shouldn't an application be allowed to prevent the back
key from exiting?
In my case we have a slightly odd design (ask sebas why we ended up with
that - he wrote it) where the top page actually morphs into two "states",
one of which is a start page where the user enters credentials, the other
one is the main view of the app once credentials were entered.
Now imagine we want to allow the user to change credentials. Simple,
right? Just go back to the other incarnation of that top page. But how do
you change your mind and go back? Easy again. Hit the back button.
Oops. You just quit your application.
The patch below fixes that.

Subject: [PATCH 3/3] Allow the app to filter the back key even at the top
level
There's no reason why the application shouldn't be able to prevent the
user from exiting with the back key.
