Largely because I expect the server should be behind nginx/apache/similar, and the SSL layer can be done there. I know it's trivial to use the right library in golang to auto-generate the correct certificate via let's encrypt, but the libraries I've used for that don't handle wildcards, which is what we'd need here. I'll update the document to make that more explicit.
