there is one legitimate choice to make in the scheduler, which is a real
honest preference:
the spread out versus "sort left" preference.

that doesn't need 15 knobs, that needs one.
I can totally buy that this might be easiest done by ripping out all
existing stuff, and then doing something relatively simple
(say, in the, "which CPU to run at" logic, a minor bias)
