Hi all, I updated the KIP to make it explicit that the Java clients shipped with Apache Kafka 4.0 would only be guaranteed to work with brokers running Apache Kafka 2.1 or newer, since they too would no longer have access to the removed protocol APIs. Thanks to Jason for asking about this aspect offline.
I will leave this KIP open for discussion for another couple or weeks or so. Please do share your thoughts given the high impact of the change.
