Ahh... That last part makes sense. This is what I was trying to get around to. If you only have a handful of designers and developers, you shouldn't be focusing on min/maxing your landing page. It's not that this is a "myth", it just doesn't make sense for a new team to worry about it vs product development.

I'm not claiming this to be truth or anything. Just in my experience. Bringing up a/b testing to my clients or teams just results in a "we have better things to do."

(I suppose being the head at a co. that does this would make it biased on at least some level).
