The NSView documentation page starts right out by saying:
NSView is an abstract class that defines the basic drawing, event-
handling, and printing architecture of an application.
(this is from <http://developer.apple.com/documentation/Cocoa/
Reference/ApplicationKit/Classes/NSView_Class/Reference/
Reference.html>). I have not seen any documentation saying that
NSView is currently a class cluster, I was speculating that it could
be in the future. In any case, when I see a class described as
"abstract" I take that to mean I should not instantiate the class
directly, and I assume the initializers may return instances of a
subclass rather than the class itself. Is that not correct? Or are
the docs wrong by describing NSView as abstract?

The problem with your category approach is that NSView is not a
concrete class, it is an abstract superclass meaning it might be
implemented in appkit as a class cluster.
Errr... no. You can easily create a plain NSView in Interface
Builder around other views, so it's definitely not abstract, and
I've yet to see any documentation stating that NSView was a class
cluster. Can you give me a URL where you heard NSView was a class
cluster?
