And yet, even for programmers, that output is full of info that is useless 99.9% of the time. That is just bad design. It is basically a debug log that is shown by default all the time, instead of written to a log somewhere for the <0.1% time it's useful.

And I point out the attitude because I've seen it for decades and seen the harm this kind of "it's just harmless extra info" type thinking has brought. I don't know what tone you're reading into it, but I'm quite literally and explicitly criticizing the attitude, not you personally.
