What we're really thinking about is efficiency of detection. Some "defects" are really things we are learning about how the technology works. If we are having to re-learn, that's a defect. One way to think about this is that testing to a specification is waste (although perhaps necessary waste) while testing to understand boundaries is quite valuable.
