Adding support for Stadia SDK (for remote input and video streaming and such) is not as difficult, as writing a Vulkan renderer in the first place, for a game that doesn't have it. Incentives are measured against the difficulty of the whole work. I'm sure, using Wine+dxvk as a first step for existing games is a lot easier than writing native Vulkan renderer. In this sense, Google can actually provide one level of incentives for native games (higher one), and another for Wine use case. I.e. developers can first release it in Wine (phase 1), and then make a native version for example (phase 2) to improve performance. What Google could do, is to provide integration of their SDK with Wine for phase 1 above.
