Oven Lock Confusion.

I enjoy making sure that when I close the oven or the dishwasher, they are locked. For some reason, I have a fear of the door falling open. In the case of the dishwasher, this is never a problem. Latching the door in the appropriate manner is always fairly easy and possible, however, the oven, I'm afraid, is a different story...

I was making cookies from my unfortunately, yet tollerable, mediocre peanut butter cookie dough, and when I put the cookies in the oven and shut the door, I felt it necessary to lock the door. I mean, the oven is only 350 degrees at this point in the cookie making process, and I feel that locking the door should at least be an option. Indeed, it is not. You may only lock the oven door when the oven is not a flaming hot inferno. Now, I understand that locking the oven door is not for everyone, but is it so much to ask that while the oven is hot enough to heat and cook flesh, it may be locked to prevent any possible incidents? And does it really make sense to put a lock on an oven when it doesn't even function at tempuratures of 200 degrees and higher?

I do believe that if I were an oven manufacturer, I would have thought a little more about installing those oven locks, and their possible, and yet non-existent, features.
