Agreed. I was pretty much assuming that a failure mode of returning to a "default" state was reasonable; I see now that this will not always be the case. Behavior on brown-out must be taken into account as a special case of this as well. Another related consideration is that with a double solenoid, you do not know know a priori which state the solenoid is in at startup; with a single solenoid, you can be fairly confident that it has returned to the default state if the power was off for more than a few milliseconds.
