The reason is: no combustible mixture makes it very shure that there is no backfiring or ignition when the prop of a hot engine is accidentily moved, even with ignition set to on.
To stop a airplane engine by switching the ignition (magnetos) off is dangerous and just plain WRONG!!!!
And of course a airplane engine is constructed to run without external power, be it generator or battery.
Those are only needed for auxilary systems!
The "Kommandogerät" of the FW190 could be set to manual override if i.e. the electric was lost.

I haven't made myself clear:

switch off procedure:

1) taxi to parking
2) ancillaries checklist (flaps, brakes etc..)
3) mixture to lean
3) throttle to idle/cutoff (if present)
4) engine stops detonating
5) magnetos off

now the engine is off

you can take the engine to idle and switch it off with the magnetos, which is not dangerous at all, it is actually considered safer because even if there is some mixture residue (you might have a faulty inlet valve for instance), there will be no spark from the plugs in case of accidental prop swinging.

I didn't know you could override the kommandgerat, where were the manual controls for the engine?
