Agreed. Especially since I'm not at all convinced that APM CPU idling
ever really worked in the first place.
And as you say, it's not a catastrophic failure even if we were to
remove it, and even if it were to have mattered on those old laptops
years ago. I think we can happily say "not worth worrying about" when
it comes to APM_CPU_IDLE.
And shutdown, suspend and screensaver should all be much easier to
continue to support - they shouldn't have any serious infrastructure
issues.
