The xdg-portal attempt was misguided and I don't beleive anyone is pursuing it at this point. Ideally drm-leasing would be managed by the login manager, allowing multiple compositors to lease connectors and run independently on other monitors, as well as being used for VR headsets. https://github.com/systemd/systemd/issues/29078.

Sidenote: I hacked the wayland protocol implementation for gnome into working at least for SteamVR, but at least with AMD gpus there is some serious bug preventing the card from performing properly. It basically throttles itself for no reason and never hits the refresh rates needed for smooth VR, especially since there is no asynchronous reprojection at the moment. So while ideally the drm-leasing problem would be solved already there are other even more important problems to solve with linux VR for now.
