React's performance are way more severe and ubiquitous and user impacting.

I'd really love to see the websites you're writing in React and lunch a lighthouse or to simulate how do they perform for somebody on a slightly slower connection or not being on the latest iPhone.

Because I know my users include bank clerks or post office cashiers on 10+ year old computers being used at work as much as people on vacation with very poor signal on the beach.

Of course, if you only experience your website from your MBP on cable you thing the issues are only at "10k rows" level.

We target <3s to usable on lighthouse mobile, ideally less but I don’t design the sites so only so much I can do about large above fold images etc. the truth is react isn’t that bad compared to latency or other issues on the kind of use case you’re describing
