I wonder what use case you're talking about, I don't have a lot of cases where re-render needs to be dealt with, unless I'm making a web app like a multi player photoshop in the browser, in those cases I won't use SSR. For most information based sites, e.g. Hacker News, Twitter, there's no need to track change and re-render, all the data can be ready on the server side like querying database or making request to third party APIs, then it'll just be piecing HTML strings.
