It's too bad ad tracking networks ruined shared JS hosting and CDNs for everyone. There's no cache benefit to it any more because browsers stopped sharing caches between sites for privacy reasons. (As Deno shows, ESM imports make a lot of sense from CDN-like URLs again. It just won't perform well in the browser because there is no shared cache benefit.)
