Yes, I don't think it's worth it other than as an exercise in byteshedding.
- removing quotes around attribute values
- replacing href values with the most frequent characters
- sorting content alphabetically
- foregoing paragraph and line-break tags for a preformatted tag
I was able to bring it from 730 bytes (330 had you compression enabled) down to 650 bytes (313 bytes after compressing with Brotli). Rewording the text might get you even more savings. Of course I wouldn't use this in production.
