IPv4 typical MTU is 1500. you are suggesting downgrading IPv6 performance (compared to IPv4) by doing MTU 1280? does not make sense to me. PMTUd issues are the exception, not the problem. But the level of exceptions are higher now than it shall be later, since we are really deploying IPv6 now, removing old stuff, fixing as we go. Think also about backbone nodes/high-end servers that are able to do 9K MTU. Change to 1280 MTU. no.
