Hi Jiunn-Yang, Thanks for the KIP! I think it's correct and pretty much reflects what was written in the ticket.
One thing to point out explicitly is that there _is_ a behavioral change. People using REMAIN_IN_GROUP explicitly now with streams groups, the member left before theis KIP and will remain with this KIP. However, I think this is rarely used because it explicitly states the (old) default. Specifically with KIP-1071, I don't think many people will use it. I consider the behavioral change here more a bug fix that we are implementing as part of this KIP, but I would still point it out in the KIP.
