It's not a hack to cold set. It's a hack to cold set badly without checking and correcting frame, dropout and hanger alignment. It's a hack to ride the wrong size wheel without cold setting.
Going from 126 to 130 is not a big deal. If you could go back to the late 70s to early 80s, many if not most of the bikes on the starting line of a bike race would have been reset to 126 from 120.
