Is "GetUserMedia.SecureOrigin" a good name for this metric?
The name of the metric currently reported by HostsUsingFeatures is
"PowerfulFeatureUse.Host.GetUserMedia.Secure".

[tommi (sloooow) - chröme, 2016/06/10 13:19:36]

Sounds reasonable to me and consistent with how things are currently being
reported - but I don't have anything else to compare against really.

         return true;
     }

     // count attempts to use it.
