Perhaps I should have been more verbose.

What I meant to say that to implement site-locals properly in a router,
the vendor should not be OK to say "we support access-lists, you can use
them to configure site-local borders" or that "we have nice firewall
products, wanna buy one?".

That doesn't seem to be in the spirit of site-local addressing, and I
could imagine a significant percentage of site-local users wouldn't do
these steps properly, leading to a false sense of security. (Thus one
factor in the argument that site-locals in with global networks are bad.)
