No such assumption is made as far as I can see.
I take Dan's writing of this to apply to GET as she is currently defined,
with any parameters encoded in the URI.

GET-with-body is not defined.
If it were defined, then presumably it would be defined which that the
effective URL included the body.
As Dan's draft mentions, "A QUERY or "safe POST" or "GET with BODY" method
has been discussed (e.g. Dec 1996 IETF meeting) but no consensus has
emerged."
