No, they aren't.
You can't hardcode site-local address filtering in every router,
or you won't be able to communicate inside a site.
So the router will need to be configured, somehow, to block
site-local addresses from being forwarded from one interface
to another. And that configuration isn't any more inviolate
than a traditional forwarding filter.
