Yes, this is something the framework team should definitely look at. Mathew did an excellent job of separating each task into it's own controller -- something I have understood was the goal with the new MVC architecture.
Lots of questions about where Joomla should go with it's MVC and component structure. This is golden.
Will be v interested in hearing Don Gilbert's take on it, too. The discussion on Don's post -- his comments and those of others
gets into why the approach Mathew took is highly recommended by experts. I believe (could be wrong!) the path Mathew took is exactly what was intended by Andrew/Louis when the MVC Interfaces and for the future of J!.
