I think fidelity is the wrong term, as the pared down website is more fidel, um, faithful to the content than the one with all the widgets. What it comes down to is the distinction between apps and pages. I want a news site to be a simple page. Maybe it has a search function and some interactive visualisations if it is fancy. It should not be able to access my camera, location, run web workers, execute third party JS to profile me, and so on. Reader mode should be built in. The best thing for the usability of the web would be IMO if the next HTML standard would be split. An ultra slim HTML6 doc mode (maybe where it is realistic that a small team could write a new browser engine from scratch), and a fully featured HTML6 app mode. I mean AMP was something like doc mode, but for the benefit of Google (restricting which ad platforms you could use) and not for the benefit of users.
