IPv6 ISPs don't need to be particularly efficient in
assigning/allocating IPv6 subnets and most of them will never need to
ask for more space.

Since when is efficiency a goal in IPv6. I always thought that IPv6 was
designed so that efficiency was no longer an issue. Instead, IPv6
enables network designers to build their networks the way they want to
without worrying about wasting IP addresses.

IPv6 is not IPv4 with more bits.
