Ismael Juma updated KAFKA-18465:
--------------------------------
Description:
Apache Kafka 4.0 will only support KRaft and 3.0-IV1 is the minimum version
supported by KRaft. So, we can assume that Apache Kafka 4.0 will only
communicate with brokers that are 3.0-IV1 or newer.
Note that KRaft was only marked as production-ready in 3.3, so we could go
further and set the baseline to 3.3. I think we should have that discussion,
but it made sense to start with the non controversial parts.
> Remove MetadataVersions older than 3.0-IV1
