> D3D is clearly more integrated into the OS than Vulkan is.

sure, but addressing the two points that you brought up would not entail changing windows _the operating system_, just the stuff that ships with it. you could easily ship swift shader along with warp and the loader library, both of those are just some application libraries as far as the os/kernel is concerned. of course now we're in the territory of arguing about "what constitutes an OS" :-)
