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

It just occured to me that AF_UNSPEC might be used simply
because "all zeros" might be a valid real bindable address
for some address family.  And using AF_UNSPEC avoids that
problem entirely.
