The Device & Sensors Working Group has asked us to review the Generic Sensor
and Ambient Light Sensor APIs.

In particular, the following request is for the Web Platform WG:

* we're seeking overall review of the shape of the API, its integration with
the rest of the platform and its usage of WebIDL (noting that the TAG has
already provided input to the generic sensor API).

Please provide feedback before TPAC (September 19) if possible.

Unless somebody specifically asks for feedback to be endorsed by this group,
comments should be made in a personal capacity.

The full text of the request is below.

Cheers,

Adrian.
