Being unpractical is the point. It's unpractical to implement tracking, anything beyond simple ads, websites with flashy or distracting designs, picture-in-picture video autoplay like news websites often do, popups, moving banners, and RAM/CPU heavy client-side scripting (or any client-side scripting, for that matter). So your website will have to do without that. And that is by design. Gemini is designed to exclude those features, because the target audience of this protocol wants to browse a web where those features are impossible to include.
