We do give the option, but it is advantageous to be able to build the 
entire set of packages for Xorg without disturbing the current set. 
Then change everything with one symlink.  It also allows the user to 
back up to the previous working version if something goes wrong.

And the user has the information to do that.

"If you've decided to use the standard /usr prefix, you can omit the
