Exactly. The ability to get a prefix immediately without being forced to
follow some kind of a registration procedure is an important property.
As long as site locals are non-routable, administrators of "non-serious"
networks (and those that are just plain lazy) will simply pick a prefix
and go with it. The solution must be such that it can be implemented in
a router stack and applied automatically. I'm sceptical even about the
willingness of network admins to voluntarily apply a hash function just
to get a quasi unique prefix, unless the protocol stack does it for
them.
This means that what we really need a site-local prefix
autoconfiguration specification similar to the link-local address
autoconfiguration.
