Exactly. This is what I can see if we can bridge this "a bit different".

True, I am dumb to miss out some points, but I think with more inputs,
more thinking, we can definitely make it generic!

Thinking out loud ( excuse me if this is dumb), At the end of the day,
how I see this benefiting a lay driver developer is : use the regulator
API for the appropriate power sources - your SoC domain, your external
regulator domain..etc..etc and ensure a very efficient (probably) run
time PM for your device. All that the Platform guy will do is iterate 
a list of domains on the platform, provide hookups, ensure constraints 
etc and the job is done. Even if the same IP is used on a different SoC,
you still ensure efficient savings in your driver itself.

Ohh. for the patch set, as I said, its only a primitive implementation.
With your inputs, we can definitely make it more efficient!
