Jumbo frames aside from the usefulness of bigger payload for mpls/tunnels etc add some value in an environment where there's some packet loss.
I would have thought it makes it worse, assuming a physical fault resulting in a constant bit error rate combined with larger packet size means higher probability that a packet is corrupted (as there are more bits in it). The resulting packet is discarded which is a bigger loss than discarding a smaller one.
If you're fragmenting and drop one packet of a 4-packet-sequence you waste the other 3 packets anyway as its gotta send the whole oversize packet as multiple fragments all over again. My guess is that is his reasoning - and seems fair... Mark.
