Yes, Alexandre has caught me out. I had completely overlooked that
RFC 2993 has a stray reference to 6to4 as work in progress.
However, it's beside the main point of that particular paragraph
in RFC 2993, which really says that NAPT44 can be useful to allow
legacy IPv4 to coexist with IPv6. That has happened, quite regardless
of 6to4.

Looking at the change made when the 6to4 reference was added:
(https://tools.ietf.org/rfcdiff?url2=draft-iab-nat-implications-06.txt)
I suspect that our thinking was a bit confused at the time. But
I don't think it really needs an updated RFC from the IAB.

Regards
   Brian
