Andrew Schofield commented on KAFKA-18984:
------------------------------------------
[~chia7712] There is no justification that I can think of. You can delete an
entire client metrics resource, or you can alter an existing one to reset a
configuration to its default manually. kafka-client-metrics.sh doesn't have a
way of actually deleting a specific configuration, which would have the same
effect as resetting to its default value.
> Support to delete specific config by kafka-client-metrics.sh
