Best way to think about it is, you probably can get away with replacing all your 15/20 amp breakers with 30/40 amp breakers in your house without going from 14/12 gauge wire to 10/8 gauge wire, but I doubt you'll be able to get your home owners insurance to cover you with it.
A better analogy, but why then did Intel not make 1151v3 with even more power pins for the 9900k if these margins are so critical?
Except that doesn't actually prove anything. When he steps up to cover peoples warranties when they do it, maybe he'll have an argument.
He proved what he set out to do. The pins can handle WAY more power than they need to.
