I can't speak for other browser vendors, but I think that license isn't compatible with Mozilla's codebase. But thanks for the reference.

Can you be more explicit about what you mean by "perfect coverage?" What set of use cases are you trying to address? Are we talking specifically 3D graphics? If that's the case, it's not clear whether that's really appropriate for the ECMAScript spec. As I say, we standardize very few libraries, usually just the smallest set needed to provide core functionality.

Just looking around, there are already lots of WebGL matrix libraries out there:

Then again, WebGL is already exposing the GPU to JS programmers. IANA GPU expert, but can you not already farm out matrix math to the GPU via GLSL?

As I say, I'll look into this, but a standardized matrix library doesn't seem as high priority to me as the rest of the binary data spec.
