disabled items in menu_links table makes Features module's "Create Feature" page very slow to load

Because Features module's "Create Feature" page shows all menu items (including disabled ones) for export, it makes the page very slow to load. It also make Feaures "Menu Links" export function unusable since there's hundreds or even thousands of disabled menu links to go through.

Can node hierarchy stop using the menu_links table in this way? Hierarchy relationship is already stored in the node_hierarchy table, why is it necessary to litter the menu_links table will disabled items? It's causing a lot of trouble in other places too. e.g cache_menu table My cache_menu table is 200MB, even my node_revision table is only 50MB. My database exploded 5x in size just because of this.
