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.
