If I imagine this as the best possible way to develop a curriculum (which it may or may not be), there is still a big problem: learning is driven by curiosity. What is curious to one person is boring to the next so the specific path from
"novice" to "expert" is very personal.
It's a curriculum, not a compulsory work load. Also, the curriculum would be updateable. I think it's often the case that somebody wants to go farther into a subject and would like to know what the standard knowledgebase is for that subject.
