Hi,

Nothing in the lower layers of the IP stack provides any "value" to the 
end-user.

Which is why they are not banging at our doors demanding "TCP!" or
"DNS!" or "IPv4".  Or, "IPv6", for that matter.

Applications need to work, and applications have learned how to survive
NAT breakage, so applications need to learn how to do deal with non-stable
IPv6 addresses.
