Hi Amran, thanks a lot for your message. I think this is a valid feature request. I've created a JIRA ticket to track it: https://issues.apache.org/jira/browse/FLINK-14856 (this does not mean this gets addressed immediately. However, there are currently quite some improvements to the configuration system in Flink, as part of FLIP-59 and FLIP-81)
