It's 136.4kB minified (react+react-dom), for a zero app is crazy. The app size that will justify 136.4kB is probably 700kB which is 836.3kB total, is also crazy. So no hello world argument because it sucks (in engineering metrics) at all range of apps.

According to https://web.dev/optimizing-content-efficiency-javascript-sta... the js size budget is about 800kB minified (1s to parse/compile). So if an app max out the budget, the framework part is considerably 17.05%.

Not bad, but if the median of react app is around 300kB which means the framework part is 45.4%. This is bad!
