1. No javascript or code execution. 2. No CSS, no colors/fonts at all from sites, they should be system specified. 3. Something a bit like frames to handle updates of the browser defined content area rather than javascript. 4. Much richer tags. Enough to make a site like HN with <comment user="flukus" time="2019-02-08">foo</comment> and to have the browser render that. 5. No Video. IME giving sites control of the display and layout is where the web went wrong.
