Has there *ever* been a confirmed attack that this feature would have

Yes.
Citation please?
I'm afraid I am not at liberty to disclose that information. Sorry.
However even back in 1993 there were projects to test the strength of PGP
Key Material based on factoring attacks. The RSA-129 project came about
through one of those discussions, and I seem to recall that at least one
RSA Key was factored after RSA-129. I don't have a reference for that
effort (and my google fu isn't working immediately).
