device units appear on the initial transaction only if some service
has a dependency on them, i.e. actively needs them for something (most
likely: for mounting them after they appear).

The "systemd" udev tag decides whether a .device unit is synthesized
in systemd for a udev device. But if you drop that for a device and a
service has the dependency on it anyway then this will just mean it
will wait forever for it, because it never shows up then anymore.
