I feared as much.  Somehow I had hoped MS had learned the lesson.

This practically seems to make site-locals totally useless due to
non-existant security in current unamanaged networks, at the very least.

Nobody can bind to site-local addresses unless he can be double sure the
upstream routers actually are configured with the site boundary towards 
the global internet.

(Without even getting into the application problems..)
