For example why can't we have auto-refreshed content standardized? Something like <section refresh-from="https://foo.bar/example-section" refresh-time="60s"> where user could accept/deny the auto-refresh and adjust the timer would make JavaScript completely meaningless for websites like Twitter.
The overall experience would be much greater: no trackers, no tab using half of your RAM/CPU to mine cryptocoins, no targeted ads, no weird behavior when switching internet connection (because everything would be handled by the browser itself, not by JS requests which may or may not randomly fail).
Gemini is a really cool protocol but i appreciate some aspects of the web like images and videos (with the builtin players, no JS please).
