They’re a bit like the UML diagrams of design. They have some utility in certain contexts but they are taught as a ready made solution without that context to students who aren’t able to relate it to real experience and end up overdoing it and misapplying it as they tend to do. It doesn’t hurt that doing it makes you feel like you’re doing something useful, it gives you a shiny deliverable, ... but in the end there likely are better ways to answer the kind of questions you really want to answer, and many of them involve making the actual thing vs making things that only serve the planning of the making of the thing.
