This actually has nothing to do with NavHostFragment, but is the behavior of NavController's setGraph().
When you call navController.setGraph(R.navigation.navigation_graph), it stores that ID and will restore that ID automatically.
If you were to instead use:
NavInflater navInflater = new NavInflater(this, navController.getNavigatorProvider());
navController.setGraph(navInflater.inflate(R.navigation.navigation_graph));
Then NavController would not restore the graph itself and the call to restoreState() you point out would only restore the back stack state, etc. but would wait for you to call setGraph again.
You're right that the inconsistency between the two setGraph methods is concerning. We'll take a look.

Description
Right now in KAPT / Javac; we check assignability without the nullability information.
Taking nullability into account is partially possible but it would be a breaking change.
Instead, we can consider
a) make a breaking change w/ a flag to ignore it b) take nullability into account in TypeAdapterStore when two things are equal
With two way adapters, it is not trivial to do
b
but it is worth investigating.
