It makes learning and navigating a new codebase much easier. So much so that it doesn't really require IDE tooling the way it does with most mainstream languages. It's harder to get lost when you always know which way is up. Consciously thinking about whether you're doing top-down or bottom-up design also flows naturally from this, for the same reason, and that seems to encourage more thoughtful, readable code design.
Is it more work? Up-front, yes, absolutely. In the long run, though? By the time I finished my first year of CS education I had already been exposed to many many examples of cases where greedy algorithms consistently produce sub-optimal results. Perhaps they aren't teaching people about that in school anymore.
