What frameworks treat HTML as an output format, and what is the input? When I see samples of React code, all the HTML (in the form of JSX) is still handwritten, just combined dynamically.
Sure - you write the html snippets by hand (and those are still very maintainable if you use inline styles). But you don't maintain the final page that might have e.g. twenty buttons, so that's not a case to optimise for.
