Taxonomy Hide ported to 4.7.5

Hello community,

i ported the core functionality of 'taxonomy hide' to 4.7.5 (don't know if it's backward compatible, but it should). What is missing so far is the grouping function.

function taxonomy_hide_help($section) {
  $output = '';
  switch ($section) {
    case 'admin/modules#description':
      $output = t('An interface for manipulating with vocabulary term list in node view.');
      break;
  }
  return $output;
}
function taxonomy_hide_settings() {
  if (!module_exist('taxonomy')) {
    $output = l(t('Taxonomy module not enabled'), 'admin/modules');
  }
  else {
    $options = array();
    $options[0] = t('None');
    foreach (taxonomy_get_vocabularies() as $vid => $vocs) {
      $options[$vid] = $vocs->name;
    }
    $form['taxonomy_hide'] = array(
      '#type' => 'select',
      '#multiple' => true,
      '#title' => t('Select the vocabularies which are hidden from display in nodes'),
      '#default_value' => variable_get('taxonomy_hide', array()),
      '#options' => $options,
      '#description' => t('Select the Vocabularies which terms should not show up in nodes.'),
    );
  }
  return $form;
}
function taxonomy_hide_nodeapi(&$node, $op, $arg = 0, $arg2 = 0) {
  if (!module_exist('taxonomy')) {
    return;
  }
  switch ($op) { 
    case 'view':
      $hidden = variable_get('taxonomy_hide', array());
      if (count($hidden) == 0) {
        return;
      }
      foreach ($node->taxonomy as $tid => $tobj) {
        if (in_array($tobj->vid, $hidden)) {
          unset ($node->taxonomy[$tid]);
        }
      }
  break;
  }
  return;
}

greetings
