So you'd vote for making non-final the default again as soon as the 
"Cocoa-legacy" is gone?

Sorry if he overlooked something, but I thought the arguments were against the 
current default…
What exactly compromises safety when a subclass is allowed to monitor usage of 
its inherited methods?
True, when a method is overwritten, the base class might lose something it 
relies on; but when this can't happen, can you point out an example where this 
behavior causes danger (damn, I actually know one, but you have to tell first 
;-).
