Not everything has to be RFC approved. If I had the need for a new protocol, I'd just use one of the dead protocol ports anyway.
I suspect firewalls blocking everything but ports 80 and 443 has a lot more to do with why so many services these days are being stacked on top of them. I used to run a SOCKSv5 SSH tunnel home when I worked for a more restrictive employer, and of course I stuck it on port 443.
DNS is even more open then Port 80 and 443. Lots of small WLAN appliances which are in the most internet cafe`s today could be easily blown by putting a vpn at the dns port
