The main “stuff” I see is that by default we get a link to About, FAQ and/or Guidelines in the sidebar menu, and the FAQ/Guidelines, TOS, and Privacy links built into the About page.
You probably could ignore them, and customize the sidebar. My concern would be that if there’s a path anywhere to navigate to /about (or if search engines are smart enough to look for it? 
) it could get crawled and indexed. And so might the links on About leading to unused FAQ/TOS/Privacy pages, whether the links are hidden with CSS display:none or not.
