Agreed. I just mentioned it as it's similar, but I won't recommended either. I don't recall leaving an unlocked terminal in the past 10+ years. It's habit that's very easy to develop and follow strictly (I do this at home even when I'm alone). At one point, I was even tracing the keyboard cable when coming back to unlock to make sure there isn't something in-between although it's not hard to hack your keyboard internally as well. Laptops robbed me of this habit, unfortunately.
