That is easy to fix:

net/ipv6/af_inet6.c net/ipv6/ndisc.c

That is complete nonsense. IPv6 is not on backburner at all, i don't think
there is any criticism on the current implementations besides not being
complete yet and TLDs have nothing to do with a network protocol.

The important part is:

Security Considerations

This document specifies that the IP Authentication Header [RFC-1826]
and the IP Encapsulating Security Payload [RFC-1827] be used with
IPv6, in conformance with the Security Architecture for the Internet
Protocol [RFC-1825].
