All our datacenter customers have their own VLAN, and get a /64 on
that, with a /60 reserved by default for "more subnets".
With "own VLAN", the customer is free to use any v6 address in their /64,
after all, there are no other customers to steal it from.

Cisco-challenged networks... Sup720 cannot do IPv6 uRPF in Hardware,
so you have to do per-customer incoming ACLs to stop spoofing at the
source. Can be done, is much more painful than "just turn on uRPF".
have you enabled IPv6 on something today...?
