tl,dr: designing cities as hierarchical trees, while perhaps efficient in the sense of transportation links, is a bad idea from the standpoint of making a cohesive city.
It has similar flaws, as well. It should be considered descriptive, not prescriptive--and Christopher Alexander is not nearly as careful around that distinction as the GoF.
