Yep, that's  an I-D.

And, it says things like "Without
   the particular considerations , PCP may not provide desirable
   outcomes.  Some default behaviours may even cause negative impacts or
   system failures in a mobile environment.  "

Got an operators with a timeline on supporting it?  How about a mobile
OS that plans to support PCP, because you will need both.  And, that
would be interesting information.

I asked around in Vancouver about PCP, and all the operators i spoke
to said no-plans, no motivation.  But, that was a small sample.

In any event, my only point is that RTCWEB should NOT be counting on
PCP.  If PCP is a tool you have, use it.  My point: it is not a tool
you have.
