We went through a protracted phase where the practical global MTU
for IPv4 was around 512, unless you wanted to reconfigure your laptop
stack experimentally each time you checked into a hotel and figured
out how to connect to the phone line. I even recall having to set the
MTU to 256 in one hotel. We may well have to accept a protracted phase
of 1280 for IPv6. Eventually it will resolve itself, as it did for IPv4.
I think that's orthogonal to the question of deprecating L3 fragmentation.
