Likewise, why does NSWindow's -windowController return 'id' and not
'NSWindowController*'?

I imagine that NSWindow's windowController returns id for the same reason that stringFromString: does—because it often returns a subclass of NSWindowController and therefore it returns id so that you don't have to cast.
