There are many third-party libs which make using Vulkan much easier, all the way up to Game Engines which abstract everything. That isn't a argument against Vulkan.
A good graphics API, even a web one, is one that provides good control over the GPU.. and to have sane standards which limit future implementation fragmentation (like shader byte-code instead of a specific shader language), and to have good debugging tools, etc.. That's what Vulkan is, regardless of how verbose it is in comparison to OpenGL.
I'm not saying you can just make Vulkan run on the web, but I'm certainly in favor of a Vulkan-subset (using SPIR-V as a shader base) becoming the successor to WebGL over one inspired by Metal and MSL.
