But the spec calls for a "null address" to be used and that's in my
understanding something different from using AF_UNSPEC.

memset(&sockaddr, 0, sizeof(sockaddr)) should give you AF_UNSPEC

But the spec calls for <quote>null address for the protocol</quote>.

That means the family for the null address is the same as the family of
the socket.

Spec doesn't match traditional behaviour then. IPv4 0.0.0.0 is 
traditionally an synonym for old style all broadcast (255.255.255.255) 
on UDP/RAW and it's certainly possible to connect() to that.
