Anything that more than two "real user" entities are going to want to use,
and *might want to inter-operate*, is probably standards-track material.
About the only reason not to do it would be if it was decided that the
design chosen was technologically flawed. However, I think NAT should have
taught the IETF (as bridges taught me) that sometimes what seems
technologically flawed is in fact just what the market needs and wants -
usually for some reason one hasn't sufficiently appreciated.
So I would generally err very much on the side of caution, and stay with the
standard in the first paragraph. (Even if it does sound like an April 1
escapee...)
