As we are trying to target 5.2 as possible (and will not support 5.0 
anyway) I would try to add yet another wrapper in t3lib_div.

So I am for doing it like this in compat_php52.php:

if (!function_exists('json_encode')) {

  function json_encode($array) (
   if (!$GLOBALS['JSON']) {
     require_once(PATH_typo3.'contrib/json.php');
     $GLOBALS['JSON'] = t3lib_div::makeInstance('Services_JSON');
   }
   return $GLOBALS['JSON']->encode($array);
  }

}

In 4.3 we can remove this again.
