I don't think its outlandish to feel moral qualms about keeping corns in smaller vivs. Some people on here use tubs for their adults, which I only reserve for yearlings or sub-adults.
I've never been a fan of cramming my snakes into the smallest possible tub in order to have more shelf room for more snakes. I don't feel right doing it. Most of my snakes are in a roomy viv compared to their counterparts in other keepers' homes.
I just recently ordered two 48" x 24" x 14" cages for a couple of my larger adult corns. Most of my adult corns are in 36" long tubs of varying heights depending on sex. Females get taller tubs to accompdate a nest box, compared to the males' tubs.
Usually too large and spacious housing only affects the younger snakes, as they generally have more to fear of the big open world than larger snakes do. I've not yet met an adult cornsnake that wouldn't eat anywhere anytime, so I doubt you'd have to worry about their stress from a roomy viv compared to that of a youngster.
I think there's been some discussion about lack of exercise for adult breeding females having more of a tendency to become egg bound, because their locomotion muscles are also the muscles that help them to expel the eggs. So that's one of the main reasons why I try to keep my snakes housed in big roomy tubs, so they can stretch out and maximize the space within and actually move about. Plus when it gets close to laying time, I get my females out and handle them every day or so and make them exercise to hopefully avoid those issues.
We all have responsibilities as pet owners, I guess I just never saw the point to keeping snakes (albeit an easy to keep species) in small containers when they certainly do appreciate roomier confines most of the time (at least in my collection). When I've moved yearlings up to the 41qt Sterilites from 12qts, they've roamed for hours upon hours, like the novelty of actually moving is new to them. Although I'm sure they're just merely looking for an escape opprotunity.
