Yeah, I was taking a bit of license with the term. The problem is that rolling your own non-crypto security is still fraught with danger, and not all languages provide good libraries that hide the dangerous choices for you. Even worse, those libraries often aren't written or audited by security experts either, which is a bigger problem.
