Answer 1

What is the point of sending HTML, which is in a form that you don't want, to the client browser and making it run JavaScript code to clean it up? This looks like a bad design.

How about fixing all your static HTML, and HTML generation, so that these superfluous
elements do not occur in the first place?

If you use JavaScript to modify the document object, do so for dynamic effects that cannot be achieved in any other way.
