I don't think that there is a direct NEC rule against them- but you can be 'tiptoeing through a minefield' with them.
Like... does the ground pin do anything? Stick one on an old K&T box, and there still is no ground.
Basements and such will still require it to be on a GFCI.
Some places actually require receptacles to be on different circuits from lights, so that might be an issue.
As for attics, where the same fixture will both provide light AND power for servicing equipment ... meeting two code requirements with one device ... well, some AHJ's might thing that's a bit TOO clever.

I'd say if it's a 2-prong, no, but if it's a 3-prong, it's OK. The problem is that if it's accessible, you can't have a bare bulb, but if it's inaccessible to protect the bulb, it's not much use for the plugs. Also, cords shouldn't be in close proximity to the bulb. So even though the fixture itself might be OK, it would be hard to find a legal application...
If they're not illegal, they should be! I put one in my attic, though. Right above the access hole, so you can reach up and pull the cord. I know, I'm a bad boy, but it's too convenient not to!

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.'
