Nowhere in my comment did I say abandon a build step?

I’m saying—if you do not have high interactivity requirements, which I would claim is most things on the web—you will encounter a lot less overall complexity shipping mostly server-rendered pages with isolated, self contained JS bundles where you need them.

I was using multi-entrypoint build steps outputting separate per-page or per-feature CSS and JS bundles long before I ever worked on an SPA, it’s hardly a good reason to move your entire UI and routing to the client-side.
