I can see though how arguably it's more applicable to personal or startup (flexible, able to pivot) projects, not so much to medium-big companies. I can see how it might be more important to implement it regardless of it being 1h or 1 week than asking whether or not it's a good idea to implement it. And also arguably the university teaching focus on these companies. That is why you have all of these fancy ways of encapsulating dependencies and wrapping them into oblivion. Funnily enough a really similar thing happens in other degrees. I studied Industrial Engineering and can calculate whatever you want about the cinematics of a robot arm but it wasn't until I set up with some friend to learn how to make one from scratch that we really knew what it was all about.
