Of course... *ideally*, but we are not there right now.

Yes, so the only question is; is this desirable or not? Personally, I
don't see why a normal person would want to enable REGULATOR and
TWL4030_CORE but not REGULATOR_TWL4030; what's the point of enabling
REGULATOR if it's not going to do anything? Anyway, these people can
still choose REGULATOR_TWL4030=n, but it *certainly* doesn't seem to
be the normal use-case. And that's the whole point of 'default y' to
begin with; to enable by default what most people should say 'y' to.
