Re: [webrtc-pc] RTCPriorityType combines relative bitrate with QoS priority, which applications may not want.

Can't you use QOSSetFlow? From MSDN:

Or are there practical limits to this?

I thought POSIX OSes do, by calling `setsockopt` with `IP_TOS` or `IPV6_TCLASS` before sending the packet.

But anyway: even ignoring the issues related to QoS and multiple congestion controllers, it sounds like we agree that the "1:2" ratios are too limiting, and that mixing this up with QoS is undesirable.
