"Following the steps in this capping example is not a guarantee that you will not spend more than your budget." "Resources [...] might be irretrievably deleted." Also it's not automatic, you have to manually write code to do it, and test it, and make sure not to break it. A reasonable implementation of this feature would be built into the console, guarantee a maximum spend, not require writing your own fallible code, and provide an option to preserve storage (at normal cost) so that all your data isn't deleted when your compute/API stuff is shut down.
