I'm not sure what you are talking about. Our software has a stub resolver that is not the one in glibc. It directly issues DNS requests without going through /etc/nsswitch.conf.
It would have been fine if it was getaddrinfo (and it was done properly) because getaddrinfo gives back a socket and that can add the scope ID to the IPv6 link local address. In DNS there is no scope ID, so it will never work in Linux (it would work on Windows, but that's a different story).
