It has been pointed out that MLM implementers have even more inertia than your average MTA implementer.  Although many header fields have been invented specifically for the purpose of aiding list management (your List-Id: and List-Unsubscribe:, not to mention Sender:), their adoption has not exactly been universal.

So you might be gung ho for big changes that will make things better, but we need to accept the fact that a substantial portion of the installed base won't change, at least not soon, and we can't ignore them.  Any BCP we produce will have to take that into account.
