SSP is an important, valuable, *optional* part of the email

This is a very important point.  When the draft says "MUST," an
experienced i-d reader will know that it actually means "x must do y in
order to comply with this specification."  That's not so obvious for
other humans, especially when pretty much all of the conversation on
this list also has the inherent assumption that SSP will be everywhere
for everybody.

There will be entirely valid use cases for which SSP will not be useful,
and may even be damaging.  Ellen's is one of these: she's probably going
to have to change her entire business model as SSP adoption grows.  In
our discussions -- especially with people who aren't fluent in the
ancient & dusty IETF vernacular -- we MUST remember that SSP will never
and can never be any stronger than a SHOULD.
