Interesting point, but it is straightforward to configure these always.

It has never occured to me to set up a list so that:

  if the sender does not publish dmarc, add subject and footer

  if the sender does publish dmarc, don't add them

and I suspect it never occured to the mailman authors either.


Really, if heading down that path, it should be "if DKIM signed, don't
munge" because I get DKIM failures on people via lists, and thus
welcomelist_from_dkim doesn't work for them.
