I was under the impression HTTP/2 would make this concern irrelevant... but I'm no expert on the subject. I suppose its a valid point.

I just don't see what the point in having support for additional js language features natively is if you're forced to use a tranpiler regardless.

If you supported only, say, 50% of ES2016, and modules you could plausibly deliver unbundled native ES6; it'd be pretty cool; but modules aren't just a random feature from the pot; there is literally no serious modern web application that doesn't use them.

So... I'm struggling to see the ES2016 feature complete map (without modules) as really meaningful for anyone, practically.
