Module doesn't save menu item's language

Here's a dirty hack to get the language field set in the menu items table based on the language chosen on the node add/edit form. Doesn't take into account translation sets et cetera, but I'm not sure if that's even necessary at this point?

/**
 * Handle the menubrowser part of nodes being inserted or updated
 *
 * @param object $node
 *  The node beeing inserted/updated
 */
function menuux_node_form_submit(&$node) {
  if (!empty($node->fmenu['mlid']) && $node->fmenu['menu_name'] == '0') {
    menu_link_delete($node->fmenu['mlid']);
    return;
  }
  $link = array(
    'link_title' => trim($node->fmenu['link_title']),
    'link_path' => "node/$node->nid",
    'menu_name' => $node->fmenu['menu_name'],
  );
+  // add language field if i18n_menu is enabled to provide a sketchy i18n implementation
+  if(module_exists('i18n_menu')) {
+   $link['language'] = $node->language;
+  }
  if (!empty($node->fmenu['mlid'])) {
    $link['mlid'] = $node->fmenu['mlid'];
    $link['has_children'] = $node->fmenu['has_children'];
    if (empty($node->fmenu['related_link'])) {
      if ($node->fmenu['link_title'] != $node->fmenu['old_link_title']) {
        $link['plid'] = $node->fmenu['plid'];
        $link['weight'] = $node->fmenu['weight'];
      }
      elseif ($node->fmenu['menu_name'] == $node->fmenu['old_menu_name']) {
        return;
      }
    }
  }

The "fix" I posted above works however, I run it on multiple productive sites without problems. However: I forked the module locally to make some other adjustments related to i18n since this aspect isn't covered at all by the module itself, but my changes are very specific, related to my projects. I would love to see built-in i18n support too, but I think this is something the module's maintainer has to look into. I shared another patch in the issue queue related to i18n which should be helpful as a starting point for a proper integration.
