Somewhere in the above message you mentioned that you think /64 is
excessive.  Have you taken the time to look at why /64 is recommended,
and how addresses get allocated inside a /64 ?

It's all to do with automatic configuration rather than manual setup
of IP addresses.  With a /64 you can just connect an IPv6 enabled
machine to the network and it will automatically configure its IPv6
address and routing to suit that network.

How many people, who still have difficulty setting their video recorders,
are going to be able to work out how to correctly configure their network
addresses and correct routing?
