I think if the single regulator case isn't just a special case of the
multi regulator case then we're doing this wrong and there will be
maintainability problems so I'm not sure if this split makes sense at
all.

So what happens if one regulator is enabled after the other and the
constraints become unsatisified?

It seems cleaner.
