Direct storage doesn’t address the majority of these concerns though. It only means the CPU doesn’t need to load data first to shuffle it over, but it doesn’t help if the CPU does need to access said data or schedule it.

Only if you’re dealing with just the desktop environment and don’t allow the user to load applications. Or if those apps also didn’t allow dynamicism of any kind, like loading images from a website
