install location of X11 apps

[Trevor Forbes]

I would like to profer, as a general rule, that all "x11 only" apps to
have the --prefix=/usr/x11r6 rather than the present --prefix=/usr... It
makes it easer to manage the separation between x and non-x apps by
paths.
That is put all X-apps in:
/usr/X11r6/bin
/usr/X11r6/include
/usr/X11r6/lib
...etc

It will also help reduce the number of files placed in /bin

What do you think?
