I agree. But that's not the case with this PHP framework (as far as I can tell). They use 'MVC' as structure for there code (or as you call it: prescriptive). And then suddenly a lightweight framework is not that lightweight anymore. So again I agree with your descriptions of the web as MVC, but MVC in a PHP framework only... I still believe that's just a hype word.

BTW I don't want to start a flame war about MVC. I just got some question marks about using a PHP 'MVC' framework.
