That would cause major breakage in the C API and is not inline with the
intention of having a Py_UNICODE type in the first place.

Users who are interested in UCS4 builds should simply use UCS4 builds.

--with-wctype-functions was scheduled for removal many releases ago,
but I never got around to it. The only reason it's still there is
that some Linux distribution use this config option (AFAIR, RedHat).
I'd be +1 on removing the option in 3.0.1 or deprecating it in
3.0.1 and removing it in 3.1.

It's not useful in any way, and causes compatibility problems
with regular builds.
