I want to say two interpretations, and I'd like you to pick one or the other:
1) SMTP in unreplacebale, but (S)MIME format email can be replaced,
being a different media type across SMTP. (Possibly a new verb
replacing MAIL To)
2) SMTP as a transport could be augmented with some transactional message
system, that in the end moved (S)MIME formatted emails.
This is in much the way that HTTP has reused headers... (but HTTP/2)
