Before we get too deeply exercised, let Margaret and I huddle on it. The issue you raised can be trivially solved by adding the checksum offset to a different 16 bits in the address, such as bits 96..127. In fact, the only reason to care which bits it is added to is to handle multi-DMZ sites - multihoming. I'm looking at GSE/NAT66, which may be a very interesting application of the technology...

This was done so that ISPs with large numbers of subscriber sites would not exhaust their /32 (or larger) allocations too soon. Since these ISPs are allowed to assign a /56 to residential subscriber sites, their initial IPv6 allocation will last a lot longer and they won't have to apply for an additional allocation while everyone is getting up to speed with an IPv6 Internet.
