The fact I get it on Wikipedia, which has had newer versions of MediaWiki for a while, is the whole reason I'm not sure it's a bug.

I wonder if there's a changelog of where it came from...

After looking, it appears it was introduced for everyone for the same purpose as a captcha in 1.28 but it might be deliberate that it's not treated as a captcha? The behavior is definitely on the Wikimedia Foundation's end, not Wikia's, at any rate (that is, it's a built in behavior of the software, not a specific-to-Wikia's-implementation issue).
