I don't remember the exact chronology -- it was a painful period in my 
life and I prefer to blank it out. :-)

Well, "mandatory-to-implement" means must-implement in software, but

requirements for software implementation, not necessarily deployment.

We'll certainly bring that up when rfc3920bis is discussed.
