Anecdata from me: I've never seen this as a security question,
I'm willing to concede that I didn't notice it because I just pick a security question at random and record it in my password database with a made up answer so that I can satisfy their test later on without using a real, guessable answer.
I've mentioned before on here; it did come back to bite me once when I had to ring my insurance company and confirm that my mother's maiden name was... er... "Hitler"!
I personally think those sorts of "security" questions are stupid and I have a standard answer to all of the security questions so I don't have to remember what I put.
