I agree that the code in your gist is tricky to follow as a result of this limitation on rest params and not easily optimised. As far as I can tell, the main argument against is that the use cases aren't compelling enough to warrant the additional complexity in the spec. You said yourself that yours wasn't a common use case and although the callback-at-the-end pattern is pretty common, that's not so much an argument for rest in the middle as much as it is for defaults in the middle.
