Echo JS 0.11.0

I'm not sure who you're referring to... Safari TP seems to have full ES2015 including modules, Chrome is ES2015 feature complete aside from modules and tail call opt.  They're pretty much all over 90%, or very close to feature complete within a release target of about 3 months.

That said, It'll take a little time for older browsers to fall off (IE and Safari being the boat anchors), so we'll be stuck with babel+webpack for a while.  All of that said, it will be nice to be able to have a build target that doesn't need regenerator or large shim libraries.
