They are really blocked on purpose, but this is not set in stone.

You could, for example, provide patches that, for unknown
(but not limited to) AFs, simply assume that the specified
sockaddr is of the generic type "struct sockaddr_storage"
(see RFC 2553). All Unixes (including OSX) and even Windows
support this type.

What we'd need is a platform dependent SocketAddress to
sockaddr_storage mapping in the runtime.
