Now is now. It's time.
Will you add the bug?

Looking at draft-ietf-tsvwg-rtcweb-qos, it's clear we want to apply the very-low/low/medium/high priority to data channels.  But we don't have any way in the WebRTC API, as far as I can tell, to set that priority.

Is this just something we forgot to add?  If so, I propose that we add it as follows:

dictionary RTCDataChannelInit {
  RTCPriorityType priority;

And it's meaning is defined by draft-ietf-tsvwg-rtcweb-qos.

If not, can someone let me know where in the API this control is?

I thought is was there, but it seems to be missing. I agree, something like you suggest should be added.

Certainly we planned on priority on the IETF side.  I could have sworn we had placeholders for it, but perhaps someone thought "it's a dictionary, we can just add it later").

Sounds good to me
