   Thanks for the PR, @ocadaruma .
   
   There is a PR we've been working on for a while, https://github.com/apache/kafka/pull/14160/files , which I think includes your fix and much more. I will see if I can get that one in since it corrects a bunch of things which are now out-of-date.

   I'm going to close this for now since it is superseded by #14160. If you find more stuff that should be fixed, please do open a new one! :)

   <p>The following features are not yet supported for ZK to KRaft migrations:</p>

Review Comment:
   I also wonder if `Downgrading to ZooKeeper` is not possible yet or already supported.
   
   Assuming all features of [KIP-866](https://cwiki.apache.org/confluence/display/KAFKA/KIP-866+ZooKeeper+to+KRaft+Migration) are covered, rollback is possible until we exit migration mode right?
