Ahhh, of course. What a cunning hiding place! :-)
However it doesn't suit my need - I want something more abstracted.
I can see there may well be a place for a simple on/off switch for some components, but then I would prefer to see it as
/sys/class/power-switch/$devicename/state
rather than
/sys/devices/platform/reg-userspace-consumer.X/{name,state}
