[media-queries] and Ambient Light Sensor API

Hello Doug, public-device-apis@w3.org and www-style@w3.org

Looking at the WD of Ambient Light Sensor API [1] on one hand and at
the IDPF Alternate Style Tags spec for EPUB3 by Fantasai (in particular
the 'day' and 'night' values) [2] on the other, I really wonder if that
API should not have its Media Queries [3] counterpart...

For instance:

feature  'ambient-light-sensor'
Value: <integer>
Applies to: visual media types
Accepts min/max prefixes: no

   Value will be 1 if an ambient light sensor is available on the device
   and 0 if not.

feature 'ambient-light-level'
Value: <number>
Applies to: visual media types
Accepts min/max prefixes: YES

   This media feature describes the ambient light level in lux. The
   specified <number> cannot be negative.

Opinions?
