There's a niche for simpler/leaner web technology.
Firefox and other browsers have a "reader mode" that simplify a page to help focus on the content. Google tried something with their own AMP service.
Gemini deserves some credit for writing a spec and for trying, even if it has many issues. I hope Gemini improves based on this kind of review and critics.
My bet is on a subset of modern web tech (eg HTTP3 + TLSv1.3 + HTM5) so client software don't have to strugle with compatibility and legacy protocols/formats, while allowing access for classic browser users. It could explitiply exclude or discourage some features (JS, WebUSB, GIF, autoplay of video, frames, 3rd party cookies, ping attribute...). This would limit distraction, better protect privacy, and hopefully keep the implementation simple.
