Indeed. I was once at a pub quiz where they used that as a 'ooh, just fancy that!'-style tie-breaker.
It's horrific to use it as a lighthearted 'fun fact', when it only came to be because of the rape of a young child.
For all we know, there may well be other girls of a similar age (and a bit older) with precocious puberty who biologically could become pregnant, but mercifully don't - because they are never predated on by an evil paedophile rapist.
