We now have HWP-passive supported, afaict. So we should discourage that.
That is; I'll care less and less about people not using schedutil as time goes on.

Why not? cpufreq-cooling should still be able to throttle the system by setting HWP.Highest_Performance no?
In which case it still needs an energy estimate.
