That'd make all the systems with currently enabled services in
network.target.wants misconfigured - network should fail on these
unless something Requires= (or Wants=) network.target explicitly (which
was marked as a wrong way to depend on network), so I think maybe some
larger announcement for packagers is in order as well, to leave less
broken systems and angry users as a result ;)
