That's true. Although, either you put it in the spec, or you'll have to
live with that JS libs do it.

The compression algorithm should definitely not go into the spec.  Just what's needed to implement, which is the buffer size formula.  The vast majority of users will compress their assets offline and deliver the right one based on the device they're running on.

Once again, IANAL, but I'm not even sure it possible to include the availability of a proprietary format in the spec. I suppose it depends on how the licensing for that format is done and for that we need to get lawyers (or at least Khronos) involved.
