The article discussed this and had an interesting point (and some stats for evidence) - that shooters waiting in the corner create space for driving to the basket.
I think the author dismissed that too casually. Anything that makes the three less valuable will result in less space around the hoop. That's not necessarily a bad thing if we want to reemphasize the mid-range shot. The only way to tilt the game back that way is to change the math on the current dunks/layups & threes meta.
