All apps I build are server-side rendered. I'm not sure how your comment changes the the question I'm asking.

IMO current browsers are more like an operating system designed for progressive loading of apps.

That doesn't mean do dumb / complicated / bloated stuff for no reason. If the best thing for your users is static html, use that.

That's like rejecting video games because the CRT was built for displaying live TV streams sent over the public airwaves.

Oof bold claim
