Right. To be absolutely clear, this draft explains how RTCWEB
implementations can satisfy the requirement F20 from Section 3.3.5 of
https://tools.ietf.org/html/draft-ietf-rtcweb-use-cases-and-requirements-15#section-3.3.5.1.
We've discussed the need for this for some time, but the RETURN draft is
the first proposal for how to actually address it.

   ----------------------------------------------------------------
   REQ-ID      DESCRIPTION
   ----------------------------------------------------------------
   F20     The browser must support the use of STUN and TURN
           servers that are supplied by entities other than
           the web application (i.e. the network provider).
