We're probably past the point in the web where formative experiments with layout are useful for most people, and most situations can be handled with a light CMS. That still leaves room for massive variance and personal control. Even just linktree levels of customization have a lot more spice than facebook. I think current big tech is still reacting to myspace allowing users to write raw CSS, and there's a lot of space for a swing back, especially given the current web's focus on "creators".
