Excellent idea. However, I think the main reason they don't review by that aspect is because there simply aren't any of those types of courses. The courses coming out of the traditional universities (on edx or coursera) seem to be very watered down versions of real university courses. For the free online, independently created courses they seem to be catering to the "immediate stimulation" crowd rather than the small group of people who want truly comprehensive online courses.
I agree though that project-based learning where the student takes an active role in the creation and development of projects is crucial. If you think about it, when the student enters the real world/work force, everything they do will be focused around projects of various size.
