I don't think sanity checks are a form of false sense of security. Ideally the way you develop software those types of credentials would never even be in your project but maybe you're testing something and they're temporarily in there (because we've all done that); a warning could let you know you're about to screw up. Naturally anyone can become dependent on anything designed to assist them. I'm not really passionated about either direction really.
