Focusing in on the contrived example re: native <form> behavior and nothing else, if given the choice I would rather remove the default behavior / "action" than adding more functionality to html. I love html, and I love writing nice clean markup that clearly defines a document, so that you can look at the html without css and js and know what information it is presenting to you. I really don't want it to do anything else.
