Maybe this can be addressed by having the Pref64 i.e. the prefix

This would allow to have the Pref64+ IPv4 address shorter than 64
bits and we can still embed crypto info in the last 64 bits as done
with CGAs
Why would the NAT64 need CGA IIDs in the bottom 64 bits of IPv6
addresses that represent IPv4 addresses?
CGAs are only useful when they're assigned to a host, not in the
address space of protocol A that represents the address space of
protocol B.
The concerns about privacy can be mitigated by using algorithms that
scramble the bits of the IPv4 address around.
Sorry, but the idea that privacy should apply to NAT64 is stupid.
If you want privacy, set up an IPsec tunnel to the NAT64. Or get an
ISP that you trust enough to let them see the destination addresses in
your packets.
