I can see both sides of this argument. It's a common and desirable practice
that application layer protocols are designed to be transport-agnostic.
Some are; some aren't. In the case of RADIUS, the original task was to
document RADIUS pretty much "as implemented" by Livingston Enterprises,
Merit Networks, and a few others. Use of the UDP transport got "hard-wired"
into the RFC. Maybe UDP is "crucial" to RADIUS being RADIUS, maybe it's an

Well, FTP runs over TCP. The similar thing that runs over UDP is called
TFTP. Maybe that example doesn't make your point as well you'd have liked.
There may be good reasons to "hard-wire" an application layer protocol to a
particular transport layer. There are also cases when that "hard-wiring"
happens as a matter of default, convenience, or lack of explicit
consideration, rather than as a matter of design or architecture. I think
we could argue ad infinitum into which category we should slot RFC 2865
However, if the WG decides that RADIUS (the application protocol) can be
transport-agnostic, I see no reason to get hung up on "naming rights".
