Some years back, I modified gre(4) to use an actual socket instead of rolling its own GRE or UDP packets. IIRC, I made gre(4) *always* create a file descriptor so that fstat(1) provided a comprehensive view of the sockets in the system. Having sockets in the system that appear neither in fstat(1) nor nor netstat(8) output seems like an unnecessary mystery/complication to me.
