The documentation does not discuss this as all, as far as I have looked through it. Googling brings up nothing. So I am wondering: is anyone doing this? Any caveats?

With a few exceptions (NSObject, NSFormatter, NSProxy, NSOperation, etc.), objects in Foundation are not made to be subclassed, unless you really know what you're doing. What exactly are you trying to accomplish? If you're just trying to add methods to the class, then make a category instead.
