In my opinion, it's not a priority to support automatic KVO, initially  
we could add support for the controller layer and uses KVO methods to  
send notifications to observers "manually" (in -setXXX: methods code to  
take an example). We would gain most of Controller layer benefits  
without "black runtime magic".
