I'd say that an SMTP extension is a complete non-starter. Having done my share of MTA hacking, SMTP extensions are an order of magnitude harder than something that just operates on the message. Even if the something needs to see what was in the envelope, that's a lot easier to do than inserting stuff into the middle of the mail transaction. That's in addition to Alan's point that even if an MTA just relays mail without changing it, now all those MTAs need the extension too.
