This can currently only provide a random IMEI only. But we could easily
recover the deleted script. But it'd be nicer to have a central
configuration for the mode.
When toggling the switch, a lock is held for a relatively long time,
preventing another toggling of the switch to be noticed. With this
change, I hope we can first shutdown the modem, wait for a toggle, and
then continue.
We're losing the abort function but I currently don't know how we would
be able to keep that functionality given that the toggle is queued and
we don't get the notification.
