Actually, as a technology, DS-Lite has merits. It has the great advantage over dual stack that the core network can be IPv6 only. An IPv6 only network is much simpler than a dual stack network. So,easier to maintain, easier to debug and therefore cheaper.
Only the CPE and the gateway to the IPv4 internet need stuff to tunnel/detunnel the IPv4 packets.
