It is about safety. These are backups to the tabs breaking, bolts breaking, etc so it don't hit the rear tire and get slingshoted into the crowd, blow the tire and slingshot the car, and stuff like that. It is not supposed to replace the tabs, springs etc. And most of us have seen the things fly off. Easy off, easy on like the freeway. It's not as easy as it is to get the cap off of a beer bottle, or the tab off of a can, but almost. A little thether humor there.
