Comment 7 for bug 1666368

The SystemD documentation still suggests to NOT pull in network-online.target.

From https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/ which is referred to in the special targets documentation, specifically the description of `network-online.target`:

> It is strongly recommended not to pull in this target too liberally: for example network server software should generally not pull this in (since server software generally is happy to accept local connections even before any routable network interface is up), its primary purpose is network client software that cannot operate without network.

This basis is what we're following in this case.
