"No one does it" is extremely relative. Take your closing remark about JavaScript: I don't run into JS warts very often at all, and I'm a professional web developer who works in it day in and day out. I guess my team just doesn't do dumb JS stuff?

But apparently lots of other people do run into them regularly, so I believe that such things do exist.

By the same token, I've heard countless reports of people struggling with the flexibility that Lisp offers, with co-workers who abuse it to create nightmarish situations. That you haven't experienced that doesn't mean no one does.
