The impact of course is a lot less for newer PnP, but for older machine there might be different story. What if the bad marks not being read correctly? The result would be "good" board being skipped, while "X-out" being loaded. That would waste mu

I guess it is a generic thing that happens after every down-cycle. If things went bad for a while the umbrella-corporations such as Dover and nowadays also Philips will sell the parts that didn't help them get back up again. So Dover sells their SMT
