I think the value of adding *application* *user* guidance to an RFC is 
of questionable value under pretty much all circumstances, fully 
analogous to adding "safe driving" tips to ASTM's automotive standards. 
I wouldn't spend too much time wordsmithing words that will never reach 
their intended audience.
