WebGPU has been supported in stable Chrome for over 2 years. I'm also really not sure what about it is much like Vulkan 1.0 (or any other version). No manual allocations, no manual state transitions, almost no manual synchronization. If I had to pick another graphics API to compare it to in terms of abstraction level and exposed primitives, Metal 1 is probably the closest.
We haven't had enough time to develop anything really.
Secondly, the WebGPU standard is like Vulkan 1.0 and is cumbersome to work with. But that part is hearsay, I don't have much experience with it.
