Isn't the trick that the WIFI driver or kernel doe most of the magic required to make WIFI work, while a modem driver typically does not know much about the modem, i.e. a cellular modem requires some "special treatment".

Dumb question: Does it work without systemd (i.e..: Do yoiu hgave some code that does all that handling)?
