When looking at it, the exclusion should be done in `ApiVersion.apiVersionsResponse()`. But how we can know there if we are using a Raft-based metadata quorum is unclear. We could brute-force send in the `KafkaConfig`, but it appears perhaps `Features` might be another way to do it. Have we considered creating a feature for that, do you know? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
