Agreed. I tried taking this to the extreme with my personal site. It's down to ~30ms on free Netlify for first and subsequent loads, always <10kb including content, with one HTTPS request per page load. No external dependencies, reasonably readable, 100% passing in Lighthouse. The highest leverage things are usually to delete anything font related, reduce or remove media and GZIP/minify. More obscure approaches include base64ing a fake favicon to get rid of the extra call, eliminate media, eliminate all requests but the core HTML static resource, inline everything, move to a faster host with lots of CDN edges, test aggressively with slow connections and eliminate until <100ms. Mostly because it's fun, also useful though if you serve a user base in developing world.
