Actually it would not.  You are assuming that there is nothing to do
with an http: URL except to attempt to GET (or POST, PUT, or DELETE) it.
On the contrary; it can also be used as a unique name in its own right.

If it is laid down, for example, that URIs of the form
"http://geo.example.com#55.959123,-3.191657" identify a particular
latitude and longitude by the owner of example.com, then that is
authoritative, and there is not even a requirement on the owner to put
something useful at "http://geo.example.com", though it is considered
the best practice to do so.  (Note that the #... part is not sent to
the HTTP server.)

They tried to pierce your heart                 John Cowan
with a Morgul-knife that remains in the         http://www.ccil.org/~cowan
wound.  If they had succeeded, you would
become a wraith under the domination of the Dark Lord.         --Gandalf
