I think it is useful for helping to more strictly determine each piece's responsibility. But if a controller/action is simply a pubsub middleware between the domain and responder, won't this mean that the number of controllers would be insanely low, since you could have one base controller shared across most domain/responders? I'm not sure that would be a problem, but it was kind of undefined as to what other responsibilities the controller would have.
