I don't understand your point.  Deterrent to whom?  Embrace and extend what?

As I said in my email, my proposal would still require the same 
semantics, syntax, and UA conformance criteria as the XHTML Role 
Attribute Module, and a normative reference to that specification.  Any 
extensions of the attribute, such as different value types or special 
interfaces (a CURIE microparser or normalizer, or a list API, springs to 
mind), would still be done in updates to the Role Attribute spec (rather 
than in host languages), so it would apply equally across conforming 
host languages.
