No, unfortunately, it's not. I'll try to put something in the
installation manual.

However, I don't think it is a serious problem. The only mail sent with
envelope from mailman-loop is sent either to mailman-owner or to the
mailman list owner address(es) directly. If mail to mailman-owner is
not deliverable to Mailman, there are more serious problems than a
missing mailman-loop alias. Thus, the only real issue is with mail to
the actual owner address(es). This mail should normally not bounce,
but if it does, and the alias doesn't exist, the DSN will simply be
dropped by the MTA because it will have a null envelope sender.

The only loss is that the DSN is not saved in owner-bounces.mbox. No
actual loop results.
