Well as you realized while writing that, "handled completely in
userspace" is not the right answer here, the event-driven tracking of
charger state from the kernel is needed to drive any userspace policy.
~   Which we now have, to "widespread critical acclaim".

What is the proposal for passing the charging on and off events
painfully tracked by the patch to userspace then?  There's a bunch of
ways like power events, APM and I well know that whichever one I pick
and implement, a mob will appear telling me it has to be some other one.
