Any comments? The behavior seems broken. At the very least its very
inconsistent with other Unixes.

Until the socket has a full final tuple it is bound to, there is no
reason to list it.

No UNIX lists a socket which is partially bound and hasn't either
performed a listen() or a connect().

Well.... I took the .c file mentioned previously, and compiled it on a Solaris 10 8/11 instance. The 25-odd sockets it created *were* listed in the output of netstat -an -- local address as *.<portnum> remote address as *.* and a state of "BOUND."

A FreeBSD (rev 8 IIRC) netstat -an seems to display them in a state of "CLOSED." I didn't check HP-UX 11i v3 or AIX 6.
