Delete redirects that are no longer in wp_posts?

This is more of a request for future functionality, but could you have a function where it would go through the redirect table, compare to the wp_posts content and flag any redirects that are no longer needed?

I’m currently doing maintenance on a company website so I can easily write some SQL for it int he meantime, but I thought it would be a cool feature for future versions of this plugin. 🙂
