Gentlemen:
We are/were having a debate (AHJ's) regarding this item.
One AHJ seems to remember an NEC prohibition (my word) on the recept/lampholder "a while back"

Locally, the consensus is "yea", but no one can pin an NEC year on the supposed change.

I agree, two prong, no; gfi'd ???, and a gray area in an attic as the service outlet and light. Cord on the bulb envelope?? Hey, it's UL; as to the validity of the ground pin?? the tester knows!
