Hi Colin, It's very exciting to see KRaft ready for production!
I see the value of marking it ready for production even with the current missing features. However, I'm worried about marking ZK mode as deprecated before these missing features are ready. It might be hard to estimate right now how much work is actually necessary to close that gap, particularly the upgrade from ZK. Deprecating ZK before providing users with an upgrade path might be sending the wrong message - when something is deprecated we want users to move away from it, so that should be possible. It might well be more than a few months to close the gap.
