why did you remove the idle

But the actual code does not actually deal with any 'state 0', does it?
It does. Not being idle is tracked by cpuidle driver as state 0
(arch independent):

I know that your new API tries to use 0 as exit, but 0 is already
taken (in all power terminology at least on x86 it is) for this.
cpuidle indeed misuses C0 as poll idle state.
That's really bad/misleading, but nothing that can be changed easily.

Ideally this should not be called C0, but expressed

Yes it should get renamed to not show:
