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.

Right, but we should target the 80-90% use cases now, and others when they become more commonly available. 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. 

Note that I am not saying that this is a bad idea - just that we should not add things because they might enable something tomorrow.
