Without trying to find the mailing lists for the IPv6 working groups,
this must have been pretty recent. I just check up on RFCs every once
in a while and RFC 3513, dated April 2003, still talks about Site-Local.
RFC 3587, from this month, talks about losing Top Level Aggregators
and Next Level Aggregators, but that's something different.
I don't doubt you though, even though it's being deployed, IPv6 is far
from completely specified. The details still move around faster than
I'll be followoing. Heck, no one really has found a good way to use the
DIFSERV fields of IPv4 yet.
