Not really, at least not if we want GDL2 to work with apple-apple-apple. 
 IOW, GDL2 will always have to find a way to hack around the current 
Cocoa API to remain compatible with WO 4.5.  I personally still have a 
strong interest in this compatibility so I'm willing to maintain these 
hacks.  In fact in this case it was as simple as overriding 
-setNilValueForKey: to call -unableToSetNullForKey: as I already have 
the infrastructure in place to take care of category precedence.
