KIP-746: Revise KRaft Metadata Records fixed several issues with the original record definitions established in Kafka 2.8. KIP-778: KRaft upgrades spelled out a clear path for handling changes to KRaft metadata in a backwards-compatible way. Overall, we feel that the next release of Kafka, the 3.3 release, will be a good time to  remove the "only for testing" warning from KRaft and mark it as ready for production.
