Quick comment: lower-level APIs can be harder to standardize than higher-level ones, depending on the diameter of the API-set and the implementation dependencies. Running native binaries requires a new compiler and a bunch of runtime API support (Pepper). OTOH adding typed arrays or binary data to JS is narrowly targeted and pays off for higher-level API builders. And the typed arrays and binary data specs are being standardized.
