I disagree, most webapps, like 99.9% I would say, are just forms, links, and pages. Meaning, they can be done with 0 reactivity and that is the most simple and straightforward way to do it.

Less code is basically always better, so if you can skip the huge amounts of JS and orchestration required by modern web frameworks, then it will be easy. People are out here using React to render static pages. It's very overkill.

Eh, there’s tradeoffs. They’re real. But I’ve done plenty of this on teams back in the day before all these frameworks and it can absolutely work. It may even be easier now with JS modules.
