If you're doing this through cloudflare, you'll want to add the response header cache-control: no-transform so you don't bomb cloudflare when they naturally try to decompress your document, parse it, and recompress it with whatever methods the client prefers. That being said, you can bomb cloudflare without significant issue. It's probably a huge waste of resources for them, but they correctly handle it. I've never seen cloudflare give up before the end-client does.
