FWIW, CherryPy has gotten a lot of criticism on this front. Our servers
are "conditionally compliant" with HTTP/1.1 (specifically relating to
Continue), but others prefer to call them broken. Just be aware you'll
get the same flak over any candidate for the stdlib.

CP's _cpwsgiserver isn't a party to that special-casing, and handles any
method, even fictional ones, equally.

However, one thing CP's WSGI server currently does *not* have is the
ability for the user to configure SCRIPT_NAME. Christian Wyglendowski is
working on a patch for that at the moment, and I think that would have
to be built, released, and stable in the field before CP's WSGI server
could be considered a candidate for the stdlib. Given how recent *that*
feature-request is (only a month or two), I think it's premature for any
server to be considered for the stdlib; WSGI needs another year to shake
out other, hidden spec-interpretation differences.
