I don't think the replacement unit I proposed was installed correctly on
your system. Could you double check?

This is the express purpose of network.target. Here's the relevant
snippet from `man systemd.special`:
network.target
This unit is supposed to indicate when network functionality is
available, but it is only very weakly defined what that is supposed
to mean, with one exception: at shutdown, a unit that is ordered
after network.target will be stopped before the network — to
whatever level it might be set up then — is shut down. It is hence
useful when writing service files that require network access on
shutdown, which should order themselves after this target, but not
pull it in. Also see Running Services After the Network is up[1] for
more information. Also see network-online.target described above.
