As for a Parking Sensor API, I don't think we want a API for any type of thing that comes about. As for Proximity API means the one for face-closeness detection on a mobile phone, I don't agree it just for mobile phone and face-closeness, we are seeing proximity sensors that are coming to the PC and tablet which has better range than just close to the face.

However, if you have evidence that a significant portion of the market actually has these multi sensor devices, then it forms a strong case for standardization (why do I feel we've had this discussion already?). I'm really interested to see if there are any camera based solutions in the wild.

We discussed this issue already in May (see: http://www.w3.org/2009/dap/wiki/FutureWork) and concluded the functionality is out of scope for v1. It seems the situation has not changed since (no devices shipping with multiple proximity sensors, no new use cases).

Given this, I propose we'll defer this functionality to v2 as agreed already in May.

All - let me know if you have concerns with this.
