[jira] [Created] (KAFKA-12886) Enable request forwarding by default in 3.0

Jason Gustafson created KAFKA-12886:
---------------------------------------

             Summary: Enable request forwarding by default in 3.0
                 Key: KAFKA-12886
                 URL: https://issues.apache.org/jira/browse/KAFKA-12886
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


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.)
