> I don't even think the dissapearing part about svelte is that important. That kind of performance is rarely going to matter before other bottlenecks. And if it really is that crucial, there's nothing stopping either react or vue 3 from doing something very similar. Vue 3 already has sfc that go through a "compile" process, and it uses getter/setters to make targetted changes. It matters a lot, especially on mobile phones with less processing power and spotty internet connection. It's a huge factor, actually. Downloading and parsing React+React-DOM on mobile phones, especially if they are not high end, is miserably slow. Also, it's not only a user experience problem, your "Google Rank" is influenced by your lighthouse scores. So I'd argue "that kind of performance" is business critical on several levels. At least in my experience.
