A large portion of said code comes from themes and plugins. Especially the latter, which seem to use (abuse) wp_enqueue_script and wp_enqueue_style like it's going out of fashion. A significant amount of WordPress related overhead would disappear if developers would keep resources to a minimum and provide a way to turn them off without writing additional code. Or if there was some built in system that tried to bundle together the CSS and JS files.
