If you return sockaddr of size 16, it is OK and will not break any
sane application.
The problem is that not all of them are sane yet 8)
So that hooking by protocol is more safe way. Certainly, it is wrong
way, because it does not allow to discover available transports,
but it is enough good in real life. Unfortunetely, really existing
applications cannot discover transports by more deep reasons
than absence of good interface 8)

IPv6 does nothing. Its address is too long to fit to 4.3BSD SIOCGIFCONF.
