The trouble, as I see it, is that we still have to look at the code before we run it. Even if it is a one-shot script. And it's just because you never know if there isn't some "rm -rf ${undefined_variable}/" lurking somewhere in there. And if I have to check it then I would very much like it to be readable.

I mean, I do get your point, sometimes it does not matter. Sometimes we could just YOLO it. But... if that then causes a big problem, even if at only 1% of the time, then I don't want to risk it. But that may just be me. YMMV
