This is odd; no idea how this hasn't already flagged, but: the CLIENT ID issued in handshake breaks connections - the auto-config handler didn't report success correctly, leading it to manifest as a protocol failure.

This is probably urgent. I also wonder whether this relates to any of our test breaks. Potentially impacts any servers with version >= 5, which... huh, also includes our entire test suite. Very confused.

Maybe this wasn't flagged before because we execute CLEINT ID as fire-and-forget during handshake? Absence of ConnectionId should definitely cause tests to fail, but I don't see any library code that has a hard dependency on it. Are we TOO tolerant of protocol failures?

We're not even slightly tolerant of them. In my local testing, it was burning the connection constantly. Protocol failures are deemed fatal.
