Angular 2 definitely aims to be more modular - the Angular team acknowledges the problem that it isn't modular enough itself. Stuff like di.js, watchtower.js, zone.js, etc. are all built with modularity in mind & are framework agnostic. I think once Angular hits 2.0 and it becomes highly modular, we are going to see a boom in development productivity. Some of what is currently in Angular is unique for JavaScript, such as the change listener pattern and dependency injection. These are things that we'd like to take advantage of with other libraries. Combining stuff like di.js with React sounds very appetizing to me.

In addition, it would appear that we would be able to use these libraries with Node.js as well.

I can only see this being a good thing.
