It does to me; it seems like dropping the original signature and
signing with the list manager site signature is the appropriate way to
go. I don't think I'd want to know that there is a use case where my
DKIM signature still passes after somebody modified headers. Good
intent aside, I see it being used for bad purposes too easily.

If you're worried about DKIM signing spam sent to the list address,
then that's a bit of a different problem, and it has a different,
non-DKIM-related solution.
