WordPress is often used to create websites which do not need feeds (RSS feeds, atom feeds, etc). Sometimes we just want to mimic a HTML website. You can disable the feeds functionality of WordPress.
How often do you update your posts just after publishing it on WordPress? For me, almost every post is updated at least once almost immediately after publishing the post or page on my WordPress blogs and websites. I happen to find some error or the other a few minutes later. By the time the post is updated, it has already been sent to RSS subscribers as well as social media platforms such as Twitter. You can delay publishing of content in various FEEDS.
