I've got kinda the opposite take - saying please and thank you helps anthropomorphize the models and is compatible with the idea that there are common behaviours that we should be applying to models and people - when I'm strongly of the opinion that we shouldn't use our experience with models at all when guiding our interactions with people.
Being polite to a model isn't like saying please and thank you to my dog when he does his business, it's like saying please and thank you to my furnace when it turns on and off.
