This is a mini-KIP proposal to allow a legacy Kafka in the 3.9.2 maintenance release to invoke an AlterConfigPolicy
in the same way when running in ZooKeeper mode and KRaft mode, thereby facilitating migration to KRaft.

Status

Current state: "Under DiscussionAdopted"

Discussion thread: here-2 and here-1 

...

• The new configuration entry will not be ported to 4.x versions where there is no ZkAdminManager component
• What impact (if any) will there be on existing users? 
  • none as the configuration would be false by default
• If we are changing behavior how will we phase out the older behavior?
  • not planned as Zookeper mode is phased out
• After a KRaft migration, the configuration can be removed from server.properties 
  • KRaft servers will ignore it however

Test Plan

Junit testing leveraging the @ClusterTest extension
