Probably because the GoF prefers combination over (?) subclassing.
Subclassing always discloses parts of the implementation of a

alternatives for subclassing, esp. delegates.
You are right in that Cocoa programmers often look to other design
patterns before choosing to subclass one of the framework provided
classes. That said, NSWindowController is one of the classes in
Cocoa designed and intended to be subclassed, so that's not a
consideration in this particular case.

Yup, this was the reason for me to write:
