I don't think so, in this case. The user is not asking for "sleep" or
deep sleep"; they are asking for a power state that meets the definition
of "standby" (which sleep does) or which meets the definition of "mem"
(which both sleep and deep sleep do). When the user asks for "mem", we
provide the lowest power mode that qualifies.
I'm willing to change it if there's substantial existing practice to the
contrary, though.
