Everything builds upon Wine, but when it comes to games it alone wasn't doing so well outside older dx9 titles.
It's mostly DXVK/Proton's VKD3D that actually allowed a lot of games to work on Linux with little overhead, both are funded by Valve. So I don't think calling upon Pareto principle in regards to Valve is fair either.
