Hi Luke, +1 for backporting https://github.com/apache/kafka/pull/19172.
Regarding the system tests, here is my take: * kafkatest.tests.connect.connect_distributed_test - These tests are flaky in our test infrastructure but they pass locally. * kafkatest.tests.core.network_degrade_test - This is not a blocker as it does not test any Kafka bits besides Trogdor. * kafkatest.tests.tools.replica_verification_test - It has been failing for a while. The tool is deprecated and not really used so I don't consider it as a blocker. However, there is already a PR inflight to improve it. Overall, system tests look pretty good to me. Do you agree?
