I really do wish I wouldn't feel the need to keep stepping in here
to manually exclude my own results from such wide brush strokes.
I'm one of those "users", and I've never even tried CFS v4 (yes).
All prior versions did NOT do the renicing.
The renicing was in the CFS v4 announcement, right up front for all to see,
and the code for it has been posted separately with encouragement for RSDL
or whatever to also adopt it.
Now, with it in all of the various "me-too" schedulers,
maybe they'll all start to shine a little more on real users' systems.
So far, the stock 2.6.20 scheduler remains my own current preference,
despite really good results with CFS v1.
Cheers
