I'm guessing that, like me, most people on this list just expect to port 587 to allow relaying for people using SMTP AUTH.
That is how I'm using it. I don't worry much about the Section 4 "Mandatory Actions" because I don't accept non-FQDN's at all (so I don't need to worry about expanding local aliases). And since I am controlling who has access to that service (by requiring AUTH), I don't care if I should happen to send something other than 554.
Is it possible to implement any required extensions to SMTP entirly via plugins?
Yes, but it is currently somewhat ugly, since the only hook available is the unrecognized_command hook (which is how tls does it). I keep hoping that I will somehow magically get the time and energy to rewrite the code to permit supporting arbitrary SMTP commands (sort of a "make your own hook" hook), but I suspect I will get a Pony sometime before that happens at the current rate...
