I guess the question could also be asked as to whether BIND honours
the host's configuration of the address selection policy - which
seems more likely than implementing it itself.
For those who missed it - OS level address selection policy won't
apply to BIND without specific code, as BIND is a recursive resolver
so won't be calling getaddrinfo(3).
