The problem is, that you only cancel standard validation. But you get stuck if you have a additional custom validation step.
If so, this feature is more or less deprecated though there was no official decision made about this until now, but Sylvain mentioned it as he added the possibility of adding validators to every widget. The flow script validator was more or less a hack,
What's decision - do we remove this (flow-only custom form validation) feature?
+1 Don't recommend the users to use such a "hack" when there is a better way. Of course we can not prevent that they use it when they modify Form.js or use their own script file.
And as Leo pointed out, our samples should reflect the changes for the custom validators too.
