This means that the envelope address will not match the From address
as far as I can see.  So I don't understand this requirement:

This is a very strong requirement to impose on users.  It makes it
difficult to present yourself appropriately if you're sending from a
different address for some reason.  (If I misunderstood the scenario
you present in the first paragraph, this may not be a problem for your
subscribers, but I would find it a major PITA if I were subscribed.)

OTOH, in most cases it should not be restrictive to require envelope
sender = Sender.
