ULA looks always interesting, but tends to end up in obscurity because
the right folks don't buy in.

Anyway, the proposal brings IPv6 down to about 40 globally routable
bits, compared to 21 to 24 in IPv4.  That's still a lot, though.

A further simplification would replace the Global ID with the AS
number.

A real improvement over IPv4 would embed distinct IDs for location and
identity of any subnet, but that would probably mean that subnets
receive less than 64 bits.
