Possible improvement to CakePHP AppModel::updateAll() ?

AppModel.php

//Add to app/Model/AppModel.php

public function updateAll($fields, $conditions = true)
{
    $fields = array_map([$this, "quoteString"], $fields);
    if (is_array($conditions)) {
      $conditions = array_map([$this, "quoteString"], $conditions);
    }
    parent::updateAll($fields, $conditions);
}

protected function quoteString($value)
{
    //don't quote integers/booleans etc
    if (!is_string($value)) {
        return $value;
    }
    $db = $this->getDataSource();
    return $db->value($value, 'string');
}
