I agree that it's definitely relevant. In theory, users can run any browser, so it's not a big issue. In practice, the web has become so complex that it's very hard to challenge established web browsers. I think we should push for simpler standards on the web, possibly "levels" of complexity. So you can have HTML-only compliant sites for which very simple HTML-only browsers suffice; sites and browsers that implement a minimum of javascript; and "full-featured" (i.e. bloated and full of adware+tracking). This or some similar proposal could open up competitiveness and options in the browser space, which I think would go a long way toward solving some of these issues.
