>             Project: Kafka
>          Issue Type: Improvement
>          Components: controller
>    Affects Versions: 3.6.2

> When we launch a fresh cluster of Kafka and Kraft Controller, no zookeeper 
> involved.
> We get this warning in the controller log:
> [2024-04-15 03:44:33,881] WARN [QuorumController id=3] Performing controller 
> activation. Loaded ZK migration state of NONE. 
> (org.apache.kafka.controller.QuorumController)
>  
> Our project has no business with Zookeeper, seeing this message prompted us 
> to investigate and spend time looking up this warning to find an explanation.
> We have that setting
> {_}zookeeper.metadata.migration.enable{_}=false
> and we still get that warning.
> In future version, to avoid further confusion this message should not be 
> showed when zookeeper is not involved at all .
