Couldn't we use link scope (or other local) addresses to local networks, and
have gateways that do 1:1 translation between those addresses and PA space ?
Call it NATv6, whatever.

Nobody is going to remember addresses by hand, name servers (DNS or local
scope as avahi) will be the rule. And DHCPv6 (or router advertisement) is
how you provide your hosts access.

Maybe internal servers, such as smbfs or NFS, could be only at link scope
addresses? No need to renumerate, and full protection from outsiders.
