I think the reason it wasn't talked about before is because React used to be better / have less unnecessary complexity than it does today. The front-end pain has grown by an order of magnitude since. I don't think HTMX addresses the fundamental problem of organizing (HTML) code into components, and/or the full-page-render / partial split. There is code duplication to ensure that every URL can render both fully server-side and update correctly client-side when e.g. hx-push-url happens (which most well built SPAs were able to do even before SSR, albiet somewhat slowly and poorly) edit: Another problem that most front end frameworks seems to have stopped focusing on is building actual applications, i.e. things you would approach with https://localfirstweb.dev/ https://localfirstweb.dev/ tools. HTMX can't help there at all.
