What's the status on this?
It's still being worked on. Until it's stable and enabled if official builds, the only way to get screen sharing on Linux is to manually apply the patches.
I've heard some people using the Fedora firefox binaries, which seem to be already-patched.
Finally, on some scenarios, pushing the video onto a virtual webcam device works (if you can stream a webcam on whatever site you're using).
We are trying to keep track of distro patches here...
I think you're referring to v4l2loopback as the "virtual webcam" option, in case anyone is searching for more info. OBS supports sharing video using it with a plugin called obs-v4l2sink, and on wlroots based compositors, wf-recorder has support too.
