I'm currently in the process of taking a lot of risk rewriting a large-ish app that I maintain to fully eliminate the use of frontend frameworks (and the larger JS ecosystem in general) and to switch to simple SSR + semantic HTML and CSS.

Using this tiny lib [2: shameless plug] I wrote specifically incorporating the "HTML Can Do That"-style realisations going into the big rewrite.
