@mdedetrich Sorry for the delay. I hope to review your PR in the coming days. Please keep it again trunk, if we also want it in 3.3, we'll backport it.

@mdedetrich The KIP was accepted in 3.3 but we assumed it would get merged before feature freeze. Feature freeze happened last week (see https://cwiki.apache.org/confluence/display/KAFKA/Release+Plan+3.3.0) so it's now at @jsancio's discretion...

Thanks @mdedetrich, the current changes look good. I wonder if we should also add an integration test. We should be able to extend `MultipleListenersWithSameSecurityProtocolBaseTest` to test duplicate listeners. There may...
