They already saw that M$/Windows was going to fuck them and started a 20+ year plan to end that. Now they are showing they thought about the hardware too. I do not like the walled garden, that needs to change but this is still better than nothing. With the news about intel possibly falling apart in the future. We might be seeing the early days of the death of x86/x86_64. It is possible at least.

A new update with app ID 3043620 spotted on SteamDB for an unknown application, codenamed "ValveTestApp3043620," includes key changes that reveal this info. The update lists several popular games, such as Left 4 Dead 2, Garry’s Mod, Kerbal Space Program, and Shadow of Mordor, which now feature "proton-arm64" and "proton-arm64e" tags, among other tags like "proton-arm64ec". There are also some other tags such as "proton_experimental" and "proton-arm64ec-vanguard", most likely referring to experimental builds still in testing. These tags indicate Valve is actively testing a version of Proton—the software that allows Windows games to run on Linux—designed specifically for ARM64-based systems. The compatibility layer is developed by Valve in cooperation with developers from CodeWeavers.
