kevin-wu24 opened a new pull request, #23151: URL: https://github.com/apache/kafka/pull/23151
### What changed Follow up PR to https://github.com/apache/kafka/commit/c274a7348fb66d1bde99566bdb072fbb52b03dfd, which implements controller unregistration. This PR adds a check so that KRaft voter set members cannot be unregistered, which can prevent weird edge cases around races between unregistration requests and feature upgrades. Voters who are unregistered and then re-register with a cluster who completed an unsupported feature upgrade thanks to the unregistration would experience unavailability, which affects quorum health. -- This is an automated message from the Apache Git Service.
