That's good research, and good work.

And I agree with the conclusion you implied:

That's the only approach that offers promise of settling this class
of problems.

Do MIME::Tools and/or MIMEDefang know about the punctuation marks
that some Windows MUAs silently ignore in filename extensions? How
about charset canonicalization, non-default (incorrect but commonly
accepted) UTF-8 encodings?
