Proton is mostly Wine, not DXVK. Wine does the translation of Windows and some DirectX APIs. DXVK translates Direct3D to Vulkan. Proton pulls it all together with some game specific patches, integration with gamescope and other Steam specific integrations.
All of this being open source means it can also be compiled for ARM and BSD. Though to get x64 games to run on ARM you need an additional emulation layer like Box64.
Though rumor has it that Valve is already experimenting with x64 emulation for their Deckard project, which is likely to be their next VR headset.
