Many people comments can be reduced to "Yes, you can shoot yourself to the foot. Don't do that". The problem, however, is whether we call ourselves "engineers", and not just "coders". Real world engineers take responsibility for anything related to their project, even if it's not their job. Flying instructors often teach "everyone is stupid for 15 minutes a day". That's why every plane control is made to prevent errors, even if other prevention measures failed. Of course, we often don't need that kind of reliability in computer programming. But in cases when we really do "engineering", and not just "programming", we want to prevent shooting to the foot, even when user points out gun to their foot and pulls the trigger. That's why they put safety switch on guns.
