Yooper- I'm going to meet you half way. I don't think the wording is there if they want the combination receptacle/cover unit to be Listed as an assembly. I think they definitely want the cover to be Listed and have a non-raised flat surface where it fastens to the box but I would accept a receptacle being installed in the field using the technique described as a rivet or locking thread type install. I think if it had to be built in the factory and Listed as an assembly they would have said it more emphatically.
As Greg said- They just don't want the receptacle to come loose.
Hey- they let self-grounding receptacles slide in 250.146(B) and I think that's really shaky.
