Exactly right.  There's no language on the point because it can't
possibly go anywhere.

That's the nature of the protocol.  You can't make any assumptions
about connectedness of any given hop.  The best liveness test is an
HTTP request, preferably a safe one, set Cache-Control according to
your requirements.
