Is it perhaps also incumbent on the folks promulgating DMARC (and its 
predecessors, and its sure-to-be successors) to work cooperatively with 
mailing list developers, rather than taking the position "nope, we break 
mailing lists, not our problem?"

I'm kind of coming to the conclusion that what we need to be looking at 
is defining an SMTP extension that addresses BOTH sets of concerns - and 
doing so in a cooperative manner that engages not just the community 
behind DKIM and DMARC, but also the developers and operators of mailman, 
sympa, majordomo, listserv - and ideally the sendmail, postfix, exim, 
qmail community.

Dare I suggest that this calls for an IETF working group?
