Agreed, but there is no difference in not being allowed to fly IFR in any capacity except dual, because your rating has expired, or because your rating is not current.
Want to open a can of worms?
Get a PRIVATE IFR rating, and you can go flying by yourself, as PIC, on a private flight, when your Command IR is out of currency, and get yourself re-current all by yourself.
