The value of WebGPUis that it's available in broswer, and also cross platform available on desktop.
Take the browser availability away and it's just another higher level Vulkan wrapper imo
Check out dawn. It’s what chrome implemented for webgpu. It uses the available hardware/api for the local hardware.
So while most systems will be using Vulkan, macOS will be using metal.
Windows will most likely be using DirectX. Much to people's surprise, Vulkan is not in fact, available everywhere. Further, there is integrating other Windows features (DirectVideo, DirectComposite, etc...)
