Hum... I'm not sure we are talking about the same thing. Of course system and embedded software won't have invariants stored in a database, the comment isn't about them. But, there isn't a faster way to fail to an invariant than to prove statically that your code fails it, or to test it before deploying. I don't really understand your criticism.
