This is why I would say that firmware updates are part of the preventative maintenance in the same way kernel updates are, if the bug was already fixed and if you had flashed this during a normal maintenance window you never would have had an unplanned maintenance to fix or recover from the problem.  Manufacturers don’t tend to update firmware without real bug reports from the field, why wait until you’ve had a failure due to some already-fixed corner case.
