The functionality of Gemini is pretty much done. People are of course free to write their own clients that do their own processing. But the standard is: if you need that, serve Markdown or HTML documents instead of extending Gemtext.
The Gemini specification is currently in an undefined state. Currently, Solderpunk is working on the final version.
Several proposals were floating around in 2021. You might still find them in the repositories below:
