Depends. When I was at GM we would resurface rotors under warranty because as per GM, if it was able to be turned warranty wouldn't pay for a new one. 60% of the time it could be turned without being too thin.
Customer pay jobs we usually replaced them because by the time the brake pads wore out it was either cheaper to replace them, too rusted between the cooling vanes, or they were technically to thin to be cut.
For my personally vehicle, I would replace them instead of cutting them unless they were like 300$ per disk and I could cut them myself for free
