But `netstat` was already broken for xinetd-started services. I get that it probably didn't affect you, but it means that `netstat` already had its shortcomings.

Now that socket-activated services may see more widespread usage, hopefully someone interested will add to `netstat` the ability to tell who is listening on the socket and not only who opened it (all the data is available in /proc, which netstat is using already).

And in the meantime there's always `systemctl list-sockets`.
