Hmm... Looks like \Symfony\Component\HttpFoundation::create() actually is supposed to this for most server environment values, including QUERY_STRING, but it doesn't appear to be happening:

        $queryString = '';
        if (isset($components['query'])) {
            parse_str(html_entity_decode($components['query']), $qs);

            if ($query) {
                $query = array_replace($qs, $query);
                $queryString = http_build_query($query, '', '&');
            } else {
                $query = $qs;
                $queryString = $components['query'];
            }
        } elseif ($query) {
            $queryString = http_build_query($query, '', '&');
        }

Closing to research a better solution.
