Yup, my bad, he actually said "people never say". But the way he presented it, seemed like he's opposed of it. But I still think it should be mentioned more in the industry so more developers are aware of it and think about it more often than not.
EDIT: Can't reply to Tommabeeng's comment (probably too deep). Yup, and I agree with the presenter's main point - that classes are not necessary in many situations, even for decoupling.
