3rd Opinion: OM1 to OM 3

Got into a heated discussion with my boss regarding the purchase of OM3 patch cables (2 meters). Our entire backbone is OM1 and so is almost every other fiber run. He also knows that OM1 and OM3 are not really compatible, but went ahead and purchased OM3 cable and argued that: because the OM3 patch cable is fairly short, it shouldn't cause a significant loss of signal and he wanted to future-proof this install. Admittedly, I get a little hard-headed about this stuff and I can't really fathom why you would do this intentionally. Is mixing MMF standards okay for short distances ? or is it a recipe for headaches down the line?
