Many RSS clients automatically discover a feed by reading a `<link rel="alternate" type="application/rss+xml">` tag in the `<head>` of any provided URL.
With Apple Podcasts new Timed Link feature and Threads new podcast link integration, I want to find a solution to make it easy to detect if any arbitrary URL correlates to a podcast episode. All we would need to do is include the episode GUID somehow.
What solution do you think has the best chance of catching on?
