Precisely why I suggest 'proving' engines while still at a safe height before the approach, under all conditions, after failure or not, is a sound idea. Of course this normally happens at busy airports anyway, but not always, and it may be very satisfying for a pilot to arrange their approach and landing such that the first application of power required after TOD is at the flare.
