The current angular2/angular2 super-barrel mostly re-exports symbols from other barrels (core, common etc.). But there are few suspicious exports in there that don't seem to be exported from other main barrels. Those are:

export * from './src/platform/dom/dom_adapter';
export * from './src/platform/dom/events/event_manager';

and

export {UrlResolver, AppRootUrl} from './compiler';

Why those exports are part of angular2/angular2? To which barrel they belong? We need to answer this question before we can kill the angular2/angular2 barrel.
