So carve up your IPv6 allocation into chunks for your previously private
subnets, setup routes for them, and firewall off incoming connections to
the private ones at your router/firewalls. You have no shortage of spare
IPs when you get a IPv6 allocation.
I'm not getting the issue. All you lose is the many real ips hidden
behind one public ip effect. They still reach the internet, they can
still be grouped together, they can still be made unreachable from the
broader world by your firewalls. What doesn't it do that you need?
