Out of curiosity, how recently have you touched on that? I was one of them until the last couple of months. I think moving to 3 now makes sense, and it's pain-free in my experience. In 2016 I hadn't made the move yet. And as recently as a couple of months ago, sometimes py2 was still the choice (for instance, Amazon Lambda didn't support 3 yet).
