If you need a shipping dashboard, then yeah, that's a very common, very simple use-case. Just hook up an API to a UI. Even then I don't think you'll make a very maintainable app that way, especially if you have multiple views (because the LLMs are not consistent in how they use features, they're always generating from scratch and matching whatever's closest).

What I'm saying is that whenever you need to actually do some software design, i.e. tackle a novel problem, they are useless.
