Definitely, and I think your concerns are valid, but if you found that loading each file on demand yielded the optimal performance for your app, wouldn't you go with it? Additionally, I think the method the author is presenting can be very well suited to both partial bundles and individual files. For what it's worth, you and I are in similar positions and it sounds like we have very similar approaches with our own apps. As long as readers understand that this is one possible solution to a nontrivial problem, I'm happy with it.
