Lmao, oh yes, let's go back to the golden age of every app having all of its logic running on centralized servers, rather being able to easily create cross platform client side distributed applications.
The "no-js" philosophy is fundamentally at odds with a future of distributed, OS agnostic, application development.
It remembers the web when the web was simpler, and ignores that that was the era of dll hell and applications being locked to specific OSes. The modern web is the most successful cross platform development framework by orders of magnitude,it's all based on open internationally agreed on standards, and it is vastly simplifying and detangling the overall computing environment / platforms that we used to be locked to.
Just use a framework like Nextjs or it's open source off shoots / clones and get the best of both static pre rendering and dynamic on the fly rendering.
