We need so understand that there are two almost orthogonal 
considerations for "HTTP":

(a) whether somebody gets the wire-format related improvements (header 
compression, push, multiplexing)

(b) whether communication will be in the clear (1), encrypted but not 
authenticated (2), encrypted and authenticated (3)

Looking at our charter (<http://datatracker.ietf.org/wg/httpbis/charter/>):

...so if we don't define HTTP/2.0 for "http:" URIs, we'll be missing one 
of the goals in our charter.
