Actually the former FP was clearly a variable length object. Anyway,
I read you to mean that chopping out a large fraction of the global
unicast space for son-of-8+8 is an option left open by this
architecture. That's fine, as long as people realise that such addresses
would contain mutable bits, with impact on checksum algorithms.
