Ask HN: Does an RSS-based Read-It-Later service exist?

I've used Instapaper for a few years and appreciate the convenience of quickly sending articles to the platform.

However recently I've been consolidating my online consumption into an RSS feed reader. It would be nice to be able to send articles there instead. In the same way that kill-the-newsletter generates an RSS feed from emails, I'd like to generate an RSS feed of my saved articles. Does a service like this exist?

Ideally it would look like this:

1. Sign up for a service and generate my own unique RSS feed URL

2. Add this URL to my feed reader

3. Save articles with this service (for example with a Chrome extension or website form)

4. See my saved articles appear in my feed reader
