Load in component default file and filename from hook_hook_info() if available

Let's say I've got a custom module with the following code:

/**
 * Implements hook_hook_info().
 */
function mymodule_hook_info() {
  $info = array();
  $info['mymodule_item_info'] = array('group' => 'mymodule');
  $info['mymodule_item_info_alter'] = array('group' => 'mymodule');
  return $info;
}

/**
 * Implements hook_features_api().
 */
function mymodule_features_api() {
  return array(
    'mymodule_item' => array(
      'name' => 'My module items',
      'feature_source' => TRUE,
      'default_hook' => 'mymodule_item_info',
      'alter_hook' => 'mymodule_item_info',
    ),
  );
}

The first hook allows all implementations of hook_mymodule_item_info and hook_mymodule_item_alter() to be placed in modulename.group-value.inc and be automatically included via module_invoke and module_invoke_all, which is awesome. It would be nice if Features could automatically tell that since I've provided my default hook, that it should attempt to set default_file to FEATURES_DEFAULTS_CUSTOM, and default_filename to the group string.
