I have plans to try it in a side project. I too am skeptical about the rewards of setting up a CRUD system like that.
It isn't that we've decided that software architecture meant nothing; rather, we settled on one architecture that is Good Enough. The View/Controller/Domain paradigm of Rails works for many projects.
You can still have an interesting business logic system that is CRUD at its core. A case management system, as an example, is CRUD at its basis but filled with business logic.
