Translation: if they applied for a franchise to run a postal service,
they'd be laughed out of the licensing court for their lack of
technical competence. Yet somehow we're supposed to accept that this
is normal behaviour on the Internet, much the same as "Korean mail
servers don't support the postmaster address"?

Excuse me, but it's not the callbacks that are getting in the way of
otherwise legitimate mail, it's those badly-configured servers.
You're saying that under pressure from your users, you're willing to
break specified procedures. We can't stop anyone from making that
choice (and occasionally we'd do the same, to be honest - after having
made a bit of a fuss), but at least let's identify where the fault
lies.

Perhaps we should publish an alternative mail domain, like
gateway-for-broken-senders.mydomain.example - or can someone think of
a more-demeaning form of words - and tell those kind of users they
have to use that until their brokenness has been fixed?
