No we couldn't unfortunately. As I said before: a lot of KMS setup has
to happen prior to registration, and most of those callbacks
(atomic_check, atomic_commit, etc.) can both happen before registration
and after. And that's a lot more difficult to deal with if we don't
have access to the private driver data for any of those callbacks.

So - it really does truly need to be tracked separately.
