Different features/architecture is precisely the issue with mobile, be it due to hardware constraints or due to lack in deiver support. Render passes were only bolted into Vulkan because of mobile tiler GPUs, they never made any sense for desktop GPUs and only made Vulkan worse for desktop graphics development.

And this is the reason why mobile and desktop should be separate graphics APIs. Mobile is holding desktop back not just feature wise, it also fucks up the API.
