I was already aware that images cannot be inserted in the DOM like you would any normal image. If you write <img src="https://my-pod.com/recipes/ramen.jpg">, this will probably fail to render the image. That happens because the image will be private, and the POD can't return its contents without proper authentication.

hopefully feed readers can treat permanent redirects as a sign to permanently update their feed URLs, then I can remove it. They probably don't, much like bookmarks don't

In the real world, we are faced with the completely unfair constraint of being human while writing programs and while debugging them, and none of these costs can ever be reduced to zero.

There is nothing wrong with building your own “service layer”, and many companies have left the Traiblazer track in the past years due to problems they had and that we think we now fixed.

Traditional CMSes are "coupled", which means that the CMS also takes care of the presentation layer responsible for delivering the content to the clients. The content and the presentation are closely interlinked. Typically, content managers create and manage their content through tools like WYSIWYG editors. The CMS then delivers the content according to the front-end delivery layer built into the CMS. Typically, a traditional CMS supports your websites but not much else.
