Marking a message "HTTP/1.1" should do that -- clearly, it hasn't
stopped folks from doing an abysmal job at implementing this
and other features. Likewise, nothing prevents this exact same
problem from re-occurring, with badly-behaving servers claiming to
support pipelining via any new identification mechanism proposed[1].

Really, I think that the best solution for this (and many other
HTTP-related problems) is to have a certification process, and
(ideally) a reference implementation. For the server validation at
least, it could even be an automated service (like the W3C (X)HTML
validator).

[1] The suggestion does, however, open up the interesting notion of
modularizing HTTP -- which would be nifty, but probably something
more suited for a 2.0 revision.
