We also have lots of bike corrals with this type of rack.

No need to be skeptical. It's as safe as locking the frame. I've never seen, nor heard of someone's rear wheel getting hacked to steel a bike locked this way. And there's no way to take the bike without cutting the lock, or cutting the rear wheel (and the tyre and the tube).
