I am not 100% sure if the PR make sense? While AK 4.0 brokers don't support older client versions any longer, Kafka Streams is also compatible to older broker version. Thus, one could use a 3.x broker, and upgrade Kafka Streams 0.11.0 to 4.0... To be fair, we would only test this upgrade using `trunk` for brokers right now, what would break as the older client could not connect to a `trunk` broker, but I don't think the broker versions actually matters for what we want to test. In the end, we test if we can upgrade KS client side, which is more or less independent of the user broker version. Thus, I am actually wondering, if we should instead rewrite the corresponding system test, to use broker version 3.9 to test upgrading older KS versions to 4.0+ client side -- This is an automated message from the Apache Git Service.
