Sometimes it’s handy to hide pages in the WordPress admin from certain users. For example, when using WordPress as a CMS, where you define a static front page and a Posts page for all the posts, you might not want users trying to edit the Posts page since their edits won’t show up on the site anyway. A common scenario I see is users trying to edit the dummy “News” page assigned as the Posts page, or trying to change the front page of the site by editing the dummy “Home” page.
