This proposal makes much more sense than Apples "Metal Only" solution (https://webkit.org/blog/7380/next-generation-3d-graphics-on-...). I liked Metal at the beginning but over time it turned out that it is just another OpenGL/DX flavor with the same old driver/performance problems. Also using SPIR as IL allows the use of the preferred shader language. WebGL Next is about parallelism and abstraction, otherwise there would be absolutely no benefit.

Can you comment a bit more on the limitations of Metal?

I've been spending the last few days reading through the docs and learning how to use Metal. So, I'm curious what you (and anyone else, I guess) perceive its shortcomings to be.

My personal biggest concern was the re-invention of OpenGL/DX features without the proper knowledge why and how these features can be used. For example I never managed to apply a skeletal animation to a indirect indexed draw call or use transform feedback loops for ray-casting or other deferred shading techniques.
