The problem is wasting space (I acknowledge your arguments, and reject
them), uglyness of the addresses, and the fact that _my_ network is not
_your_ network.

I'm already running non-/64 subnets on my personal networks.  I'm also
running non-/64 subnets on my $work networks.

mandating /64 subnets in the _architectural specification_ is a bug,
period.

IPv4 got rid of classful subnets in 1993, IPv6 can join the last century
as well.
