When someone makes a game for Stadia they don't really care if it works on linux or Vulkan in general. All they care is that the game works on the custom hardware and drivers Google/AMD provides for Stadia. That is the only platform they will test that version on. (This is very similar to how console development happens. You have a fixed set of hardware so you just develop for that without a care for anything else really) Sure the distance is smaller then starting with the Windows or Xbox/Playstation versions but there is still a lot of work to get it to work on any random pc someone builds.
