In a twin, to me, altitude doesn't matter that much anyways. If you're proficient, you feather the engine and continue on single-engine. As for a single-engine plane, sure more altitude gives you more options. But I'm assuming we're on the ILS for a reason, namely an overcast layer or other clouds. In this case, again I don't see much use for extra altitude, as you can't see where you're going to land anyways, negating the extra advantage gained by the altitude.

I do see where you're coming from, but in my experience, theory doesn't always equal real life conditions.
