The 'war on native' has multiple fronts and this post is just reporting on one of them. For many apps, I agree that the items you've mentioned are the most significant and progress is also being made on these fronts (e.g., GPU-acceleration of some CSS transitions are already in Firefox; more and more DOM APIs are being exposed to workers). For other apps, though, especially ones using WebGL like games or authoring tools, raw computational throughput is the most significant.
