I've seen this claim before, and when I looked into it, I found that
AF_* constants were used not only in socket(2), but in 21.ipc in the
PSD, as well as in most examples of network code I could find.
Looking at a random sample of programs in the NetBSD tree now, telnet,
ping, xntpd, inetd, and ftpd all use AF_* constants.  The only program
I found using PF_* constants is route.

I think trying to split the namespaces of address families and
protocol families is a lost battle at this point, and is only likely
to generate confusion.  But I guess the single unix spec might
disagree with me.
