Another way of looking at it is, if the receiver wants to forward other

on the recipient to ensure that the MTA doing the forward on his/her

That sounds reasonable to me.
Most recipients are not capable of doing so, and most forwarding sites do
not have the necessary mechanisms.
It's probably easier to deploy fixes to forwarding sites than to
deploy SPF/Sender-Id to the whole net. In all the discussion about
multi-hop message forwarding, I never understood why it was a good
thing for the final recipient to bypass all of the intermediate hops
for any bounce.
I would say that deploying fixes to forwarding sites, so that they
properly forward messages, is outside of the scope of MARID, but none
the less is a topic which should be explored. Once those sites are
fixed, many current objections to MARID protocols & deployment would
disappear.
