I think this is a terrible idea. I can envision many situations where a host would need both a site-local and a global address. > In fact, I am suggesting that all routers and hosts treat > site-local unicast addresses exactly like global unicast > addresses, and that we administratively restrict the use > of site-local unicast addresses to non-globally-connected > networks. I am comfortable with this. It's roughly what we do with RFC1918 addresses today, and it has worked fine for many people. Link-locals are not routable, but site-locals are within the site, and since hopefully nobody will invent IPv6 NAT, filtering site-local addresses at the edge of the site seems the appropriate solution to me.
