It could be produced, but it actually would be difficult for many entities to procure.
Being able to say, in an RFP, "RFCXXXX Yellow Profile" would be perfectly
acceptable to international trade agreements.   The users of the profiles
that become RFCs will also be relative easy.   Then the waters get murky when we get
to other profiles that might only be published by vendors and consortia.
They don't have standing in trade agreements... some ITU types claim that
RFCs actually don't count.

Anyway, in every other security area, we have looked at multiplicity of
options and decide that we don't want every option.  We've gone to either
crypto suites being explicit, or UI suites where we don't present the user
with all possible options.

I'm just asking for the same thing.
