Userspace doesn't have to know anything about how the platform is
configured. It just reads standard and documented attributes and
reacts on those.

I disagree but I'll let Anton to decide which is better and how it is
supposed to work.

Btw, I think you should also check those places where
power_supply_changed() is called for the supplies and make those
conditional to what is registered.
