Why is the Meteor.install(1.3) api better than webpack in meteor?

Cross-posting from here:

I genuinely look forward to see how using ES2015+ imports and exports meets the goals. Recognises webpacks importance and eases its integration until a viable alternative that’s supported by the wider community, not just meteor. Provides for one central place to configure the entire build system with full transparency. Makes it possible to opt-out of costly backwards compatibility.

@benjamn Carry on, I love your involvement and the direction you are taking to lead meteor into the node npm eco system and the ES2015+ modules and standardisation. Thanks. merry Xmas.
