I think they are really talking about the things that are screwed down. I know that is always the last thing they install around here since they tend to walk away in spite of being fastened in place.
A few years ago there was a rash of "walking" A/C condensers. You couldn't seem to keep one on the side of a house.
I would certainly agree things like the fridge, washer and dryer should not be required for a CO since the customer may want their own in there. Builders usually just have a couple models available and buyers of McMansions usually want something $pecial.
