Because dragImage is the old (and likely soon to be deprecated), single image style drag setup and the pasteboardWriter version is the modern multi-image drag set up. Ever notice how when you drag a file around in the Finder the drag image will morph as the drag moves between windows with different view styles etc? Or how the drag images change positions relative to the mouse as you drag multiple files around. That is the multi-image drag setup. Single image drags can’t do that.
