Famous last words. :-)
what do you suggest?
Some language that tells implementers whether they can make shim6
packets that result in IPv6 packets bigger than 1280 bytes. For
"Shim6 signalling packets may not be larger than 1280 bytes,
including the IPv6 header and any intermediate headers between the
IPv6 header and the shim6 header. One way to meet this requirement is
to omit part of the locator address information if with this
information included, the packet would become larger than 1280 bytes.
An implementation may impose administrative restrictions to avoid
excessively large shim6 packets, such as a limitation on the number
of locators to be used or a limitation on the CGA key size."
