Mayuresh, The Compatibility/Migration section says to upgrade the clients first, before the brokers. Are you talking about implementation or deployment? Do you mean to implement the client changes before the broker changes? That would imply that it would take 2 Kafka releases to implement this KIP.
Or, are you saying that when deploying this change, that you would recommend upgrading clients before upgrading brokers?
