Do you mean IPv6 deployment has fully stopped?
DS-Lite is needed in some situations,
But regular dual stack works very well, too,
Thank you for demonstration of self-inconsistency.
A problem of IPv6, among many, is that it can't properly handle hosts
with multiple (IPv4 and IPv6 or IPv6 and IPv6) addresses, a.k.a.
multihomed hosts.
As the proper support for multihoming needs careful and fundamental
design at the IP, transport and application layers, latter tweaking
of DS or DS-light can not be useful.
