Jose Armando Garcia Sancio commented on KAFKA-12886:
----------------------------------------------------

Discussed this with [~DavidA] . This is not needed for 3.3.0 but it is needed for 3.4.0. Marking it as a blocker for that release.

> KIP-590 documents that request forwarding will be enabled in 3.0 by default: https://cwiki.apache.org/confluence/display/KAFKA/KIP-590%3A+Redirect+Zookeeper+Mutation+Protocols+to+The+Controller. This makes it a requirement for users with custom principal implementations to provide a `KafkaPrincipalSerde` implementation. We waited until 3.0 because we saw this as a compatibility break. 
> The KIP documents that use of forwarding will be controlled by the IBP. So once the IBP has been configured to 3.0 or above, then the brokers will begin forwarding.
> (Note that forwarding has always been a requirement for kraft.)
