On mailing lists, If I was running one, a submission to the list after satisfying whatever criteria I use for selection should then be propagated with a single DKIM signature with the assumption that the list itself is the author of this single distribution as opposed to re-signing every DKIM signature that shows up on a submission. It will be reasonably trivial to implement and make verification much simpler.
