How does that turn into a spec? I understand we say "don't do that", but
then someone will go and do it anyway. Is the idea that a message with
multiple From: is out of scope of SSP?
Some relevant changes would be to section 2.3 to remove references to
multiple From: and change them to say that multiple From: is outside
the scope of SSP.
In 4.3 add a note to all and strict pointing out that if you publish either
of those, you better not send multiple From: mail.
Since SSP is about self-imposed limitations on what a domain does,
I don't see what the dilemma is in the strict or all practice saying
that they don't send mail with multiple From addresses. Considering
how rare and out of date this practice is these days, I can't imagine
that anybody would even notice.
