I've implemented this pattern a handful of times, and if done in a team I think it manages the complexity of large software projects in a way the traditional MVC pattern simply cannot do. The real value of this kind of architecture is not the reliability, scalability, or performance advantages (even though they are significant), it is the elegence in the way it manages complex systems and the associated business logic. The cognitive gains here are innumerable, and may even increase the velocity of a team provided the underlying infrastructure is in place.
