I don't know if the core is going to get split. There might not be a reason (overhead with memory, more to supervise). It's kinda like MVC but I think it follows more closely to the control/convergence loop you are talking about (and from there, Promise Theory), whereas MVC don't really have that control loop. On the other hand, Operators are essentially non-core controllers. They can be highly specialized to a specific system (etcd, kafka, postgresql, etc.) Same with service catalogs.
