The great irony of this (and fwiw, I completely agree, and I work on the angular core team...) is that by embracing platform features in ng2 we've opened up a mess of other issues to learn. A good example of this is modules. Angular 1 had its own module syntax (partly because modules weren't really a thing when it started). You could write scripts, concat them together and go. In angular2 we embraced ES6 modules, which means a developer has to deal with loading and bundling etc. One nice side effect here though is we can leverage more tooling from the rest of the JS community (eg, the great work of webpack) rather than having angular-specific solutions.
