Even with flex we still don't have a good way to center a list of div's. In fact the intuitive way, `justify-content: center;`, has a hidden foot gun that to this day breaks countless sites on mobile: content overflowing to the left of the parent container is entirely lost, whereas content overflowing to the right is scroll-accessible. And there's no easy fix for this! (Please Cunningham's Law, please...)

I cannot fathom how data-loss by default could ever be considered a logical answer to "hey guys we need need to start from the ground up to come up with a system for arranging elements because the old way was so busted".
