I think the code requires a working light.

Inspecting, designing, or installing I try to get along. I don't see this as being an important issue. I don't care one way or the other.

(Like John Steinke I think it is wise to test the lights as soon as possible. I put in cheap lights and switches prior to drywalling for testing. I remove them for the drywallers and put them back in as soon as that work is done. Workmen really like to see what they are doing.)

Too many of us think code compliance is a blood sport. In reality, a lot of it does not matter.

I expect at some point someone will ask: What is a "habitable" room? Answer: It is one with some attributes including a switchable light.

So for the most part having no switchable light is not a code violation. It simply makes a room not "habitable". There is no part of the code that requires all rooms to be "habitable".
