Vin,
That's a good point. I'm more curious to see what kind of problems develop with nuisance tripping of the AFCI. It is designed to open when arcing can cause a fire and is supposed to be able to tell the difference between a "good" arc (switch turning on) and a "bad" (dangerous) arc . We'll see ...

They probably only mention bedrooms as a minimum. I'm guessing that it's because they want to give you a little more protection in the place where you are sleeping. By the time a smoke alarm goes off it may be too late to get out of the room.
