Lianet, Thanks for the KIP. I think this is a desirable goal, but it seems premature without a plan for Connect. Removing the config for regular users while allowing it for Connect seems problematic. While we figure the details of that and the deprecation story for the classic rebalance protocol, we could still agree to a log line during start-up recommending `classic` users to switch to the switch to `consumer` (after appropriate testing).
