Have you actually tried creating a custom NSView, because this is simply not the behavior I've observed in the last 10+ years as a Cocoa UI programmer. The only reason to override hitTest is if you want a view through which clicks pass through under certain circumstances (i.e., it has a non-rectangular shape or a built-in shadow through which clicks should pass to underlying views) or if you want to handle clicks that are actually destined for one of your sub views. A plain NSView will do all the correct hit-testing for subviews and itself by default.
