we may want to have "enable_generic_sensor" for this (as e.g. enable_webrtc)?
(to allow control for smaller chrome/webview footprint)

[Mikhail, 2016/08/19 09:29:55]

We'd like to keep it as a runtime-enabled feature, so that try bots can compile
the code, and developers can easily enable it and provide early feedback for the
new API..

[timvolodine, 2016/08/19 16:02:30]

This would allow to enable on platform by platform basis when actual platform
implementations are available. There is not much to feedback on if there is no
implementation for a particular platform ;)

I don't feel strongly about this though, guess android would be the most
footprint-sensistive.
