As someone who setup a discord streaming like service to use alongside Mumble, this is very exciting. I couldn’t get anything involving webrtc working reliably, but the only broadcasting clients I found were web browsers and OBS, so I am interested to see how this compares!
What I eventually settled on was https://github.com/Edward-Wu/srt-live-server with OBS and VLC player, which gives robust streaming at high bitrate 4k60, but latency is only 1-2 seconds
