The WebGL working group has given input to Vulkan pretty early on in the process, but aside from a couple of broad requests the general message was "Don't dumb anything down on our account."
We're too deep into WebGL 2 to be distracted much with what WebGL Next looks like, but certainly the idea of basing it on next gen APIs has been discussed. Here's the thing: it will probably be impractical to try and expose a ~1:1 mapping for Vulkan and friends on the web like we did with WebGL and GLES2/3. I'm expecting that anything we do build will require some pretty heavy shimming if you wanted to do WebAssembly builds targeting it with Vulkan/DX12 C++ code.
As such my gut feeling is that instead of trying to mimic any particular next gen API on the web we should probably build something that feels web-native (Vulkan definitely does not!) while still retaining the best ideas from the current crop of APIs. Of course that puts a tremendous amount of spec effort on the WebGL working group, and I'm not sure we're currently equipped to handle that.
But as I said, the current focus is WebGL 2. It's a near-term, very realistic goal that will open up significant new GPU capabilities for developers. Avoiding that work in favor of focusing on a next gen API would be doing the WebGL community a huge disservice.

Waiting until the Vulkan spec is cast in concrete before we start to
consider the web implications would be to repeat history here!That's quite a good point. Even though WebVulkan may be far in the future, it'd be helpful if the Vulkan WG took input on security from the WebGL WG so that an eventual integration with the web does not become a massive pain in the posterior. Actually, given the rather dismal state of security of native apps on desktops overall, considering security implications of Vulkan doesn't just benefit the Web...
