Hi all, I've created a KIP to add listApiVersions support to the AdminClient. This will allow us to update the BrokerApiVersionsCommand tool and more importantly allow users to detect API support and build flexible client applications: https://cwiki.apache.org/confluence/display/KAFKA/KIP-522%3A+Update+BrokerApiVersionsCommand+to+use+AdminClient
As always, feedback and comments are welcome! Thanks
