To provide some historical background:

This particular deliverable mentioned in the current Charter is one of the spin-offs from the previous Charter, "System Information and Events API - an API to access various system services e.g. battery level, network status, etc.”:

http://www.w3.org/2009/05/DeviceAPICharter#deliverables

If we drill down into the now shelved System Information API, it has a setter to modify "the current value of a system property”:

http://www.w3.org/TR/2010/WD-system-info-api-20100202/#widl-SystemInfo-set

And one of the system properties is brightness:

http://www.w3.org/TR/2010/WD-system-info-api-20100202/#widl-Display-brightness

There is also a bit to figure out if the "display is currently blanked”:

http://www.w3.org/TR/2010/WD-system-info-api-20100202/#widl-Display-blanked

By looking at the current and previous Charter, and the shelved System Information API (that was published as a FPWD ~4 years before being shelving, passing CfE), it seems we’re not too far off.

But would be great to get an official blessing.
