<front> Breadcrumb is removed with no option to add it back

If the module's intention is to remove the breadcrumb then it should be an option for users to reenable it.

Line 923-ish

    // Breadcrumb navigation:
    $breadcrumb = array();
    if ($tid) {
      $breadcrumb[] = l($title, 'forum');
    }
    if ($parents) {
      $parents = array_reverse($parents);
      foreach ($parents as $p) {
        if ($p->tid == $tid) {
          $title = $p->name;
        }
        else {
          $breadcrumb[] = l($p->name, 'forum/'. $p->tid);
        }
      }
    }

Just skips right over the 'home' breadcrumb.
