Not like that, for intance, if a cocoa app implement it in an nsview subclass and didnt call super's removeSubview: and got recompile with GS then anything in GS that call this nsview subclass's removeSubview:, assuming it is an ordinary GS view, wont work properly. eg.

AppView addSubview:aView then later
aView removeFromSuperview will invoke AppView's removeSubview: w/o calling GS's
