Well, Xorg 7.0 is currently deployed in Gentoo, Ubuntu, and Fedora's
developmental branches, with more to come. So a great many apps are
building and working with it as we speak. I'm sorry I forgot that
/usr/bin/X11 is a symlink to /usr/bin (thanks to Colin again for pointing
that out) so hopefully that'll put at least one issue to rest :-) As for
the include location breaking things, I can imagine it but most build
systems should be looking in /usr/include for headers anyway...

This is true, but breaking third party packages has never been a huge
concern for Debian (or myself really ;-)

Thanks for putting this together!
