If you're factoring stuff out of an existing implementation it'd be good
to explicitly do that - this both shows where things came from and also
means that you can show that the existing user works with the new code
which is good.

It is a bit but I think that's solvable with some refactoring in place
(eg, pushing things into a smaller struct embedded in the main regulator
one and then moving them out).  I might look at it myself if nobody else
gets to it first...

Well, if there's a refactoring out of the regulator code going on I'll
need to look at that anyway.
