Per DAS charter feedback: Where we already have an existing Web APIs, e.g., Geolocation Sensor, we would prefer the working group cease work on those items and instead focus on evolving the existing specifications.
As is evident with the Geolocation API, implementers have continued to make significant privacy and security enhancements to existing APIs, and those enhancements have made their way back to the W3C. As such, we feel it's unnecessary to have duplicate specifications.
