The sunset is built into NAT444 itself, because it breaks stuff:
http://tools.ietf.org/html/draft-donley-nat444-impacts-01. Folks will
only do it as long as they have to (and they will have to, regardless
of this block being available).
PS - It is probably not a coincidence that one of the folks who has
done a bulk of the research on NAT444 authored this proposal.
