OLD:
Note that, for reasons discussed in [RFC2993] and Section 5, the IETF
does not generally recommend the use of Network Address Translation
technology.

This has several ramifications:
NEW:
Note that, for reasons discussed in [RFC2993] and Section 5, the IETF
does not generally recommend the use of Network Address Translation
technology for IPv6. Where Network Address Translation is implemented,
however, this specification provides a mechanism that has less architectural
problems than merely implementing a traditional IPv4 NAT in an IPv6
environment. Some problems remain, however, and the reader should consult
Section 5, [RFC4864], and [RFC5902], for the implications and approaches
that help avoid all types of NATs.

The stateless approach described in this document has several ramifications:
