Me neither, but one never knows.

One can ask, but collaboration usually requires compromise.

There are deep-seated social and trust reasons that some in the IETF prefer IANA 
registry based URNs to http: URIs.  Just as many in the library community prefer 

In the final analysis, which does the greater harm:  using two different 
namespaces for essentially the same information, or using a namespace that is 
not directly dereferenceable by a common browser?

I note that the DOI community have a convention of mapping DOIs to http: URIs - 
maybe this is a form of compromise that can be a basis for closer collaboration?
