What I am saying is that there is a difference between the two statements:
"I am capable of doing x" and "I will use x". The former is a hint, the
latter is what actually is agreed upon.

The classic example is news servers where on connection establishment you
get a message saying "this server supports POST", but this can at any time
be overruled by the posting policy on any of the news groups serviced by
the server.

I guess the question really is whether the server is seen as the
authoritative party that can act on behalf of the resources it exports, or
whether it just happens to be the most specific resolver for a particular
set of resources.
