I'm helping somebody with a site and I've noticed that all the main pages are wrapped inside a form. I mean:
<body> <form> [ everything in the page ] </form> </body>
Now I'm an experienced frontend dev, and find this markup horrendous. It's technically permitted, as a form can contain any flow content, but it's semantically horrible. Most of these pages don't even contain form child elements (input, select, etc.). However, in this case I'm only helping them with usability and findability, I'm not re-doing their frontend code.
Will this weird use of a form mess up search ranking, or otherwise impact on automated parsing of a page, such as in assistive technology like screen readers?
