And does it make security assurances making it suitable to expose to the web?

I know a bit about DirectX and OpenGL, and I wouldn't expose a direct interface to either of them on the web. Does Vulcan make security and isolation assurances? If not then it is useless.

Obviously there has to be a ground up rethink with security in mind. The standard won't be the same API, just like WebGL isn't the same as OpenGL. It's just, where it's possible to, you use the same API. The point is why not start with a starting point you can use on potentially every platform?

There's no way Apple would ever allow Metal proper to be ported to PlayStation or Windows, so you're limiting yourself to at best two platform coverage targeting this new standard. Vulcan will, hopefully, work on every platform. At least subsets of it, with shims. No way Metal ever gets there.

Vulkan has validation layers - that are transparent to both app using the API on one side and to the driver on the other end.
