Part of my interest in what you wrote in the link I passed stemmed from my imagination (or fantasy) where I saw opportunities arising to finally step away from the straitjacket of the browser oligopoly, with wasm et al the enabling technology to that. Yes, it would be a lot of work. A lot of things would need to significantly mature to get robust UI development frameworks, and it would be a bit like before the web, alien to many. But right now, things aren't good either, as you also referred to just now.
