Apparently, my memory looks like a swiss cheese, full of holes

What i was thinking about was the server compromise in 2015 where Theymos explicitly asked everybody to disable their secret questions

You should disable your secret question and assume that the attacker now knows your answer to your secret question.

However, you are 100% correct, the secret question isn't technically disabled... But using it will lead to a locked account.
