The whole purpose of the minimum MTU was to give space for tunnel headers (1500-1280). I'm confused by that statement. https://tools.ietf.org/html/rfc7676#section-3.2 indicates that a GRE tunnel on IPv6 and carrying an IPv6 payload works with a PMTU of 1280, and AFAIK it is among the larger tunnel headers. What tunnels does a PMTU of 1280 not work for?
