 I thought about this when reading through #26276. When a child theme (or a
 plugin) unregisters all menu items, `current_theme_supports` still returns
 true for menus, which can cause certain weirdness with the UI:

 * If widgets are not supported, the Menus menu is still visible
 * The "your theme has no menus but you can use a widget" text is not
 displayed on the Menus screen
 * The "Theme locations" label is visible on the Menus screen but the list
 is empty

 Since `register_nav_menu()` adds theme support, I think
 `unregister_nav_menu()` should remove it.
