Problem is that by deciding not to take the SPF_FAIL at face value,
*you* are the one adding yet another layer of human randomness - and
this one will make it less likely that the system will ever work
"properly" -- admins whose sites are causing the false positives will be
less likely to ever find out and do something about it etc.
Really. If they say it's a fail, reject it. That's what they're
(politely) asking you to do.
