IPv6 is another case though. Here you have mandatory PMTU for all
This is a myth. It is quite possible to have a IPv6
implementation that does not require PMTU discovery. You
just fragment all your traffic at the network MTU. If fact
there are hooks in the BSD advansed API to allow you to do
this on a per socket basis.
DNS servers, for one, need to be able to disable PMTU on
