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.
