 Hi @TimothyBlynJacobs,
 Thanks for looking into it. The reason it shouldn't be cached is let's
 imagine that you are creating an app or something which fetches the data
 from the API to show in the app or something like that. Now if the API
 endpoints are cached in a CDN then that app will only show the data that
 it gets from the cached endpoints. Moreover, if the data is cached and you
 add/update something inside your website and then inside Gutenberg, you
 are trying to add a hyperlink or find something which is not present in
 the cached content, this might lead to an issue.

 It is kind of the same reason sitemaps shouldn't be cached so that it
 always gives the latest and most updated content. Only the things that get
 rarely changed like static pages, posts etc. should be cached. Do you feel
 otherwise?
