The paragraph I quoted from the RFC seems to suggest that the authors of 
JSON boxed themselves in with respect to extending JSON.  The reason 
being that a conforming implementation is given free reign to extend 
with "non-JSON forms or extensions".  That would seem to prevent any 
extension.

Keep in mind, JSON is a proper subset of ECMAScript which means the 
likelihood of extension going outside of ECMAScript would be extremely 
unlikely.  I don't expect JSON is ever going to change.
