Many end-stations work around this problem by sending packets no longer

IPv6 1280 may itself not be fragmented, but it may end up in multiple IP
fragments within an IP tunnel if the tunnel cannot assume an MTU that is
larger.

So if you have tunnels, fragmentation services are always ultimately
required.
