In other words: there's no 'penalty' for having a value in the AUTH=
parameter the MTA doesn't sufficiently trust enough. So then, what's to
prevent a forwarder from doing?

C: MAIL FROM:<bla(_at_)example(_dot_)com> AUTH=forwarder.org

You would want

C: MAIL FROM:<bla(_at_)example(_dot_)com> AUTH=mailbox(_at_)forwarder(_dot_)org

A receiver might want to whitelist only selected mailboxes at
a forwarder (e.g. their own).
