Modern premium diesels have an electric coolant heater that in cold weather brings the engine to operating temp faster and allows for the cabin heater to work. The rest of the benefit of a grill cover in winter may just make it easier for the thermostat/system to work, but perhaps may not be necessary. Can't think of a reason it would interfere with anything in the dead of sub-zero winter, so it shouldn't hurt. I would be careful not to overheat the all-aluminum engine if the temperature becomes more human.
