Actually, if you look, most of the configuration stuff is ACTUALLY on
/var.  

$ ls -l /usr/X11R6/lib/X11
lrwxrwxrwx   1 root     root           14 Jun  9  1997 /usr/X11R6/lib/X11 -> /var/X11R6/lib/


The thing that they are striving for with the distributions is to make
it possible to do things like mount /usr as a read only filesystem.
