Umm. The side effect wasn't documented, because nobody even *thought* of it.

If people had thought of it, it wouldn't have happened. So harping
about documentation is kind of pointless.

The real question is whether there might be some other option
(documented or not) that people might have used and just accidentally
relied on the fact that /proc never even bothered to look at them.
