For cold winter riding you need more than a couple of panels (depends what you mean by panels), it's best if it 100% covers any forward or side facing part of you with windproof material.
But otherwise - yeah, I agree with you, waterproof for below freezing is not at all necessary. It just happens to be correlation with windproof and breathable material.
