DS-Lite is there for when the ISP runs out of IPv4 addresses to
hand one to each customer.  Many customers don't need a unique IPv4
address, these are the ones you switch to DS-Lite.  Those that do
require a unique IPv4 you leave on full dual stack for as long as
you can.

You forgot the tunnel brokers.
