I've submitted suggestions to some people but I believe with the workers it should be possible to create your own custom pull/push CDN because of the granularity controls they have added. It used to not be possible to interact with the caching layer but since they have added controls for that (about a year or so ago)

Also your link is missing a trailing slash (which is odd that their router doesn't add that). https://developers.cloudflare.com/workers/reference/cache-ap...
