What we need is support for optimized/hw accelerated versions of JS libraries in browser. Eample: A page declares that it will use library foo, e.g. <lib name="foo" version="^1.0"/>. Browser, e.g. firefox, looks into common repository and sees that there is two versions of "foo": one generic, and one optimized for firefox-x86_64, with native code, so it used optimized version instead. Of course, code must come from trusted source and be signed, to reduce risks.
