Gemini the protocol is still a bit mysterious to me. Why not use plain HTTPS and just serve a new text/x.gemini MIME type? Or even serve plain old text/html and enforce no-JS-or-CSS in the Gemini client.
Part of the goals of making it so tiny, as far as I understand it, is that a normal person could reasonably implement the entire thing from server to client. Going full HTTPS and HTML is a bit of a lift for a single person in a short period of time
