It seems possible to do agile, TDD, and/or refactoring all without this practice of “following a single use case from start to finish throughout the entire application”. That’s all this is, an evocative name for the suggestion that taking a single use case through the entire system from beginning to end, implementing just what’s necessary at each step, is a good way to program.

I think it has benefits but you also hit on the biggest risk, if you aren’t careful you’ll end up writing spaghetti code, except now your spaghetti is made of steel which is way harder to untangle.
