That the model isn't notifying the view through an event system is splitting hairs. The GOF book is much maligned I think because people insist on taking each pattern completely literally down to the last detail. GOF's pattern (GOF didn't create it but they discuss it on page 4, I thought I was crazy until I just checked just now) is specifically "MVC, and because we only know about C++^H^H^H Smalltalk graphical libraries and not very much about stateless HTTP systems yet in 1993, the model notifies the view of changes too, how else would it work ?" IMHO. It's an implementation detail, it's not the essence of the pattern.
So if a JS framework is now doing MVC that includes the concept of "model notifies the view", sure call it "classical MVC" or "model-notify-view-controller" (MNVC). Shrugs.
