rational for getUserMedia on MediaDevices

In the latest version of the draft, there are two ways to call getUserMedia() within the NavigatorUserMedia.

#1:	NavigatorUserMedia.getUserMedia();
#2:	NavigatorUserMedia.MediaDevices.getUserMedia();

Could someone share the rational why we need the 2nd option?  I couldn't find any spec bug that led to the change.  It seems it also kind of limits future extension of getUserMedia () beyond the media devices.

Best, Shijun
