Mostly that's for driver comfort, there isn't any benefit for the EFI vehicle's engine. Also, just because the coolant temperature gauge is moving off its stop doesn't mean the oil is warmed up. Oil pressure is lowest and therefore the oil is least protective and slowest to flow at idle.Ok, so what's the big deal of warming the car until the temp gauge moves? At that point heat works so you defog/frost everything.
