Hi, According to the [symfony best practices part on form](http://symfony.com/doc/current/best_practices/forms.html#handling-form-submits) it could be great to only have one function to do the "job" of this part before `if ($form->isSubmitted() && $form->isValid()) {}` after `if ($form->isSubmittedAndValid()) {}` I know the the isSubmitted is only here so that the logic is more understandable when reading, but is redundant to write both, no?
