I've not heard of such a thing.
That would have been the size for aluminum. But we are past that idiocy.
Many circuits now are required to be 20 amp instead of 15 amp, so those would need that wire size, anyway. Some AHJs may require everything else to be 20 amp as well. Where are you located?
Some AHJs require MC instead of NM. Chicago is one of them.
