I'm not sure if we will change the html output of the form builder forms.... probably not.
The good thing about forms built in this way is that we can include them in solutions and allow theming through css without having to edit the html.
If you want a simple form with your own html, then you should not be using that wizard.
We could at some point in the future create a wizard that does everything else but works on your existing form. That would be the more likely route we would take to support creating a more simple html syntax... or I guess making it easier for you to use one.
We appreciate the feedback.
