Could we add a third parameter to hook_token_value when called with a field?

Here is the code that's responsible for this now (includes/content.token.inc):

function content_token_values($type, $object = NULL) {
  $tokens = array();
  if ($type == 'node') {
    $node = $object;
    // Prevent against invalid 'nodes' built by broken 3rd party code.
    if (isset($node->type)) {
      $type = content_types($node->type);
      $node->build_mode = 'token';
      $node->content = array();
      content_view($node);
      // The formatted values will only be known after the content has been rendered.
      drupal_render($node->content);
      content_alter($node);

      $field_types = _content_field_types();
      foreach ($type['fields'] as $field) {
        $items = $node->{$field['field_name']};
        $function = $field_types[$field['type']]['module'] . '_token_values';
        if (!empty($items) && function_exists($function)) {
          $token_values = $function('field', $items);
          foreach ($token_values as $token => $value) {
            $tokens[$field['field_name'] .'-'. $token] = $value;
          }
        }
      }
    }
  }
  return $tokens;
}

The neccessary modification would be just:
- token_values = $function('field', $items);
+ token_values = $function('field', $items, $node);

This way when extracting the value for a field's token we would have access to the node. I want to add some translation support to content_taxonomy through a "content_taxonomy-term-translated" token. I have found no other ideas how to get hold of the node's language in hook_token_values.
