Hopefully they'll somehow support Proton and Valve devices. Trying to run older windows-only games bought on GOG with launchers like Heroic is a bit of a hit or miss, despite the Steam releases of the same games having somehow a bigger chance of working out of the box. I guess there are some weird differences between the default Proton Runtime and the proton-ge/wine-ge builds.
I use proton experimental to run most windows tools with no linux support. Small script in the script nautilus folder and there you go "run-win.sh" for all (util a native tool emerges).
I'd love to see it, too. There are a few Gists floating around supposedly letting you run a third-party game using proton, But everything I've tested fails with little to no usable debug indications on what's going wrong.
