Hence the question: did an unfixed BIOS ever make it into a shipping
production system? Because if it did, we do have a coverage hole.


Right, and the answer to your question is: there is a *chance* it did.. From internal discussions, I could
gather that the fix went into BIOS code earlier for desktop/mobile versions than it did for server versions;

So there is a chance production systems (desktop ones) might never see the issue, but server ones will, as
BIOSes spun only from now onwards will have the workaround..
