I'm lumping various in as well, which I'm not aware of Mailman being
able to remove.
I think there are others that fall into the same category, but I don't
recall them at the moment.

I agree that headers should not be modified between the sender and the
recipient. The catch is, I believe the mailing list is the recipient
and a subsequent (re)sender of a very similar but different message. As
such, I think that DKIM (and related) headers in a message going to a
mailing list are unrelated to DKIM (and related) headers in a message
coming from a mailing list.
