I think this is designed for OTT video broadcasting and not so much video conferencing. RTMP remains the defacto standard for push ingest, although that it changing with the wider adoption of HEVC, which RTMP can't carry.
FWIW, maybe I am just on the leading edge of the "changing", but I am specifically excited about WebRTC for video broadcasting due to not only how devices now have hardware support for HEVC but also for the lower latency and lower barrier to entry afforded by WebRTC. WebRTC is a protocol with a widely deployed implementation that is already tied to people's cameras, not a use case, and has absolutely no ties to video conferencing.
