You beat me up to it. I have the same thought.
However, what is described is exactly what a regular PMIC has.
They already have their own language for exactly this purposes.
(At least I see that in a few Intel SoC-based platforms.)

So, after all it may be not a bad idea But would be good to have it
standardized (if it's even possible :-).
