The actually looks like a simple single controller action using a view model. Nothing really stops you from implementing other abstractions like ORMs, state machine, authentication, web service calls, etc.

I actually think you could build a relatively well organized large project with not much more than this really needed.

You could, but I suspect that inevitably you would wind up having written a framework to organize and manage that complexity, just an ad-hoc and poorly designed one.

True enough, building crappy over engineered frameworks in big projects is inevitable ;-)
