Using the distinction of paste as copy vs paste as move, instead of overloading the cut metaphor is a better choice semantically. When you cut text or images from a document with ctrl/cmd-x the content is deleted immediately. It’s weird and inconsistent that in windows the files get greyed out and if you don’t paste them they... eventually look normal again when you put something else in the clipboard? Modifying the paste with option on mac is also consistenT with option switching between move and copy while dragging files.
