JavaScript wouldn't be able to consume those resulting objects, so it would be pretty diminished as an alternative to JSON. Object keys are all strings.

  Not that I find this idea useful for otherwise limited DTO format, which JSON is, but JS has Map, which may be used for such maps.

    Sadly because arrays are not immutable you can't meaningfully use them as Map keys. You'd need a tuple type, which does not currently exist.
