That's convoluted logic. Count on having no reverse. You may end up flying that approach single engine with limited assymetrical reversing capability. You may find it's a wet runway or icy runway with definite assymetrical reversing capability. You may find you only get one engine into reverse. You may find that reverse isn't available at all. If you plan for th elandin gwithout reverse, you're best off. Don't count on something that may not be there. Same way we plan for takeoffs with an engine failure. Don't count on reverse being available for a rejected takeoff, and never count on it for landing.
