Why would anyone want to do that?  Fragmentation is broken.

I might be somewhat sympathetic to the underlying goal if fragmentation
had any value whatsoever, but I just don't see that.


DNS server deployments are probably the worst offenders in this area
because you *cannot* run a stateless IPv6 UDP server.  The protocol
simply does not allow it.  In the real world, this is a protocol design
error, and not a problem with server deployments.
