I've had this same discussion with some EC's and other inspectors. Some EC's in my area automatically install pull chain fixtures at the scuttle hole and others do not. I did ask on EC who does not do it why and he stated - that seeing how there's no "flooring" or pull-down stairs, the attic is not designed for storage.
I do not challenge them on this as it makes logical sense. If I see some type of flooring or a set up pull down stairs then there better be a light up there.
I know an inspector that will not pass a rough in inspection without seeing the pull chain fixture trimmed out.
