Will having an jump-suit at night for incontinence make my father be less likely to go on his own during the day as he currently does?

My father tends to remove his pull-up at night and there is a "mess" in the morning that the aide has to deal with - cleaning him as well as sheets. The Assisted Living Center called and recommended "jump-suits" for night wear that cannot be removed. Won't this start a downward spiral that will lead to his total reliance day and night on "pull-ups". During the day he goes to the men's room and attends to his needs on his own. (This night time incontinence and jumpsuit recommendation came during a week that he had a virus and a 99.7 degree fever. He is 90 years old.) Isn't this recommendation premature? I am fearful because "incontinence" is a "discharge criteria" from this particular Assisted Living Center.
