Godot can do arm yeah but there will be a slight hiccup in that godot xr opengl requires the multiview extensions that mesa (amdgpu, freedreno) does not currently support. So only vulkan projects will work as of right now. https://gitlab.freedesktop.org/mesa/mesa/-/issues/10712

Getting a godot steam frame export working should be reasonably straightforward otherwise as it is all just openxr. As it stands though with waydroid you can literally take any android openxr apk that doesn’t use meta specific extensions and it will just run out of the box on frame.

Valve have their own in-house engine and in the past they have used unity to make XR stuff like “The Lab”. They’ve never officially done anything at all with godot though.

I think the “insane people” they were referring to are the people who “think Americans politics are the best model”?
