Agreed -- just like indicated in my email from 2006-10-18:
there is no reasonable way to add mandatory requirements
without changing version numbers or breaking conformance
of existing implementations (regardless whether server or client).
imho to drop to require broken legacy stuff (basic auth) seems
feasible, to add to require the impl of any mandatory auth scheme
seems not.
Moreover I would consider the introduction of such a requirement
a regression due to the existence of applications with 
"legitimately anonymous" usage of http (see my aforementioned mail
to the wg list).

Kind regards
