That is a very bad analogy, for a "fair" scheduler change requests along the lines of "app. X does Y, and gets an unfair amount of CPU" and should be dealt with promptly. Change requests like "app. X does Y, and I want it to get an unfair amount of CPU" should be solved another way. We didn't drop SELinux because random uid=0 processes could no longer re-write my /etc/shadow file, because that was a desired result.
Looking at it another way if you create holes in the algo. so that Xorg can walk through them, then so can any other piece of code. The correct fix was pointed out, if Xorg needs more CPU time than "normal" then just tell the kernel that using the interfaces specially for that purpose (Ie. nice).
IMNSHO CFS got into the kernel because Ingo wrote it, and basically no other reason. That's not entirely a bad thing, but it's not entirely a good thing either and doing "unbiased" reporting pretending otherwise isn't helping anyone.
