What are the current and planeed Implementations of the Geolocation Sensor API

[Tom333Trinity]

I can find not find any UA/Browser that has implemented the Geolocation Sensor API or has it on their roadmap.

As any new functionality has been deffered to a mythical version 1.+ And no one intends to implement this version, what is the raison d'etre for the Geolocation Sensor.

As spec'd it is simply incapable of supporting background geolocation and is serving onl as a distraction and a speed hump to progress.

Apart from W3C who has shown any interest in this?
