We've really not encountered anything that has any issues here outside
of what's supported in the constraints already (basically what voltages
can be set and if the supply can be turned on and off).  I'd be pretty
surprised if we did TBH, it's hard to do something radically different
with a single piece of silicon which is the abstraction level we tend to
be operating at if we are controlling regulators.  AFAICT a higher level
of abstraction is generally going to go along with physically hiding the
regulators even in a DT world.
