As we all know, the NEC bans 'keyless' lampholders in clothes closets.
I suspect that, prior to the code actually making that change, some mis-information circulated in the code seminars as to "upcoming changes."
This would not be the first time folks "though" the code said something that it did not. For example, I once encountered some folks who just "knew" that Flammables Storage cabinets "had" to be yellow!
That's why ... whatever your own opinion may be ... code doesn't say it unless you can cite it.
Indeed - and I know this is not often the case - every inspector ought to be able to cite his authorities EVERY time, and refrain from 'shooting from the hip.'
