equating it to be merely like HTTPS in terms of publishers giving up control over their content. Where did you read that? I was under the impression that SXG is more similar to things like IPFS, where you can have content signed by its origin (or in IPFS, content addressed by its hash). Once that is achieved, any other site (e.g. a CDN like Google or Cloudflare) can cache and serve it securely and with authentication. You can sign whatever content you want with SXG, it isn't limited to AMP.
