INPUT_REQUEST not implemented yet - but NB throws a hint on direct usage of $_REQUEST.

So basically, how should I implement $_REQUEST, if I should not use it directly? RIGHT, there is filter_var(); but guess what? It still throws a hint.
I saw the report on throwing a hint on the direct usage(234280), but I cannot agree with it. As long as INPUT_REQUEST and INPUT_SESSION is not implemented, there should not be a hint on direct usage.
The best possible solution imho would be to test if $_REQUEST or $_SESSION are used in a "filtering function" or not.

"Filtering functions" should be
filter_*, is_* and isset()


Here is a simple sample code for a complete filter_has_var() alternative which should not trigger any hints (at the moment, the line with isset($_REQUEST[$key]) does):

/**
 * Checks if super global contains key
 * The following values for TYPE are possible:
 * - INPUT_POST
 * - INPUT_GET
 * - INPUT_COOKIE
 * - INPUT_ENV
 * - INPUT_SERVER
 * - INPUT_SESSION
 * - INPUT_REQUEST
 * 
 * @param integer $type
 * @param string $key
 * @return boolean
 */
function issetSG($type, $key)
{
    switch($type)
    {
        case 'INPUT_SESSION':
        {
            $r = isset($_SESSION[$key]);
            break;
        }
        
        case 'INPUT_REQUEST':
        {
            $r = isset($_REQUEST[$key]);
            break;
        }
        
        default:
        {
            $r = filter_has_var($type, $key);
            break;
        }
    }
    
    return $r;
}
