From what I can tell, it really makes no difference to the WAS. My H was definitely cake eating. He was coming and going from the house, deciding at the last minute whether we wanted to come for dinner if he had nothing better to do, taking left overs back to his place, etc. When I changed things up, I am not sure that it really phased him at all. Now he just eats out all the time. He only has to clean his own room at his parents and do his laundry, so he is not fully experiencing living on his own. But even if my H was fully on his own, I think it would make no difference to his mindset. I dont think that it will teach him a lesson, not until he starts really looking at himself and what he is doing. I am sure that my H could go months living off of fast food and buying enough underpants and undershirts to ensure that he can go weeks without doing laundry.
