Wine (which Proton is based on) has had support for Wayland since version 9.0 (about half a year old). Admittedly it’s not even enabled by default, but it works and I’ve played Path Of Exile through wine’s Wayland backend. There’s talks to ship the Wayland driver along X11, but not enabled by default yet, since there’s still some issues before they consider it on par with X11 backend. Proton might take longer, since I don’t think Valve will enable that before they add Wayland support for the Steam client.
