Review Comment:
Maybe does it make sense to create the method `registerSharedStates` without
`restoreMode` and use it here? In my opinion, it makes sense since all usage of
`DEFAULT_FACTORY` uses always DEFAULT restore mode. And secondly, in general, I
think that this place is not about `AfterRestore` it is used at any time of
lifecycle(but I can be mistaken here). The single place which, in my opinion,
`AfterRestore` is `CheckpointCoordinator#restoreSavepoint`.
This idea allows reverting half of your changes I think.
WDYT?

Review Comment:
I don't really sure that `SharedStateRegistryImpl` should know something
about `RestoreMode` and especially its connection to
`highestRetainCheckpointID`. Maybe is it better to use
`highestRetainCheckpointID` as the second parameter here instead of
`RestoreMode`. And `CheckpointCoordinator#restoreSavepoint` can calculate this
`highestRetainCheckpointID` based on the `RestoreMode` paramater which totally
makes sense since `CheckpointCoordinator` know everything about restoring.
WDYT?
