I'm seeing a loophole in IPv6 by way of providing a local /64 which
is effectively scratch space. This would prepare the way for geographic
routing when the table space growth goes exponential again.

Positioning information is a good source of automatic address assignment,
and there's machinery (DAD) helping you to deal with rare collisions.
