What I don't understand in your comment is why you implicitly assume
that the IPv6 users would not have IPv4 access at all, and therefore
their IPv6 access must be able to react all the IPv4 services.

AFAICS, there is nothing stopping from deploying IPv4 w/ private
addresses alongside with IPv6, and IPv6 could even be used dominantly
in the network (if that's felt to be desirable for a political
reasons, or to gain experience) if the typically used services such as
HTTP, SMTP, DNS, etc. could be proxied by ALGs at the border.
