I think this should only happen when a client disconnects without issuing the LOGOUT command. So it can be viewed as an error condition. The extra output was added, to support debugging such situations. It could be argued it is a more common use case to want to know the issue, than not, but it is a matter of opinion. Maybe a setting to disable it could be considered.

For reference, these are the commits that break your parsing:
