I don't think I would run out and BUY any just for this purpose, but if you still have some around you might want to hold on to them for making repairs to broken traces or small modifications with toner transfer boards. Might be quicker than re-printing & re-fusing. Cleaner edges & more uniform than a etch resist pen.
