Vulkan itself is what it is now: an abstraction of (reasonably) modern GPUs on a very low level. It is certainly very useful in that it allows applications to use GPUs in ways that are very efficient and simply impossible with older APIs, especially OpenGL. The flipside is that this flexibility and the intentional thinness of the abstraction makes it hard and actually undesirable to check the validity of the API usage in actual production use. That's why the debug layer is an optional layer and not part if the Vulkan loader. I need to check out a few things, but if WebGPU prevents access to a few hairy bits of Vulkan like explicit synchronization and memory management (the Vulkan app has to provide that), it might be securable. There are still some benefits over OpenGL left like the entire pipeline state being expressed in pipeline objects. I don't know about DX12 or Metal in practice, so I will not comment on that.
