Actually, a router can forward link-locals between interfaces on the same link. In particular, a router can forward a packet with link-local dest and/or source back out the interface from which it arrived (and presumably generate a Redirect too). If you are implementing link-locals properly, it's really very little additional code to support site-locals. At least that's my experience.
