Lubomir recently implemented ipv6.method=shared which uses IPv6 prefix
delegation. He would know better why that implementation was chosen
over NAT64.


NAT64 in Network Manager would have exactly one use, and that would be to validate that something you are testing can pretend to have only an IPv6 address while talking to IPv4 services. PD implies that v6 connectivity already exists, so nat64 would not come into the picture. 

Some of the code might still be reusable though. I'll check.
