I think Iljitsch missed the point about privacy. Consider an IPv4 enterprise network manager that wants to gain IPv6 access. Embedding the internal IPv4 addresses in the IPv6 address makes these addresses public, while previously they were private. In a stateless scheme, they also become reachable.

I'm not seeing this.

vXuser ----- routers ------ vXserver

v6user -----  NAT64 ------ v4server

In the first case, the addresses are visible everywhere. In the second case, the destination address (in one form or another) is visible everywhere. How is this suddenly a privacy issue?
