No, but AIUI the reaction was more like "Hey, HTML 5 doesn't say anything  
about escaping <script>/<style>, does that mean that it doesn't support  
escaped <script>/<style> and thus my pages will stop working in browsers  
implementing HTML 5?".

(The first </script> tag would close the script element.)

(FWIW, this:

    <script><!--
     document.write('</script>')
    //--></script>

...works too and is allowed per HTML 5. Well, except that the written  
</script> tag then results in a parse error.)
