Honestly, that's a terrible workflow for me. Due to the nature of my work, many times I need to tile 2, 3 or 4 windows on the same screen so I can view them all at once. Flicking quickly between them instead of having them all static in front of me is a UX nightmare that gives me eye strain just thinking about it.
I have no idea how people mange to multi task efficiently by flicking and not get headaches, or on desktop with a mouse and keyboard, but maybe Apple thinks most of its customers are content creators who should just be focusing on one app at a time and never need to tile several. I guess I just wasn't meant to be an Apple customer.
For my type of work, I much prefer the Windows/Linux way of having the flicking option for laptops but also great out of the box tiling built in.
