This command would be useful to implement switching the modem to e.g.
'OFF' power state in ModemManager, where the user should only try to
externally cut power to the modem device. I believe that the whole idea
is to let the modem know that the power is going to be cut, so that it
does IMSI detach, power off radios, and make sure that all non-volatile
memory is already written.
