>
> `ClientQuotaCallback#updateClusterMetadata` is invoked by 
> `KafkaAPIs#handleUpdateMetadataRequest` only. However, that is a zk-only API 
> and hence, `updateClusterMetadata` is never executed in kraft mode. That 
> brings two issues:
> 1. CustomQuotaCallbackTest needs to be rewritten hugely in order to migrate 
> to kraft
> 2. Should we deprecate `updateClusterMetadata` directly in 4.0? or make it 
> work on kraft mode or introduce new API to replace it
> Regardless to '2', we can enhance `DynamicClientQuotaPublisher` to support 
> `ClientQuotaCallback#updateClusterMetadata` when handling `newImage`.
