Dual stack is not a transition, it is an addition. By adding IPv6 to
your network you get closer to transition, but it does nothing to
help a pure IPv6 client get access to IPv4 resources. Running an
IPv6 Internet parallel to an IPv4 Internet was a good idea for
transition 10 years ago when there was a chance for IPv4 traffic
to just fade away, as IPv4-only devices became obsolete and
were decommmissioned.

But not today. Nowadays, in order to qualify as an IPv6 transition
you have to have something (Teredo, 6to4 gateways, NAT-PT) which
will help interconnect the IPv6 and IPv4 Internets.
