For what it's worth, regarding scope, my perspective is that the document
does not create any new protocol extensions or API points.  Its only
purpose is to lay out in detail the expected interaction between
externally-provided TURN servers (like those found by TRAM autodiscovery)
and WebRTC, which is currently extremely under-specified.  Specifically, it
explains that externally-provided TURN servers are _proxies_, not just
additional TURN servers like those listed in the RTCPeerConnection
constructor arguments.  Treating these servers as proxies (in the
particular manner specified) allows us to preserve (and enhance) some
important performance, connectivity, and privacy properties of WebRTC.

This document only imposes requirements (of any strength) on WebRTC
implementations that intend to implement a mechanism for using TURN servers
that were not indicated by the application.  It does not demand that all
browsers add support for such a mechanism, and it does not specify a
preference for any particular TURN configuration mechanism.
