Critical-path is, sadly, a reliable series of depressing self-owns.

I mean yes but for that size I wonder if the critical path is 100% critical, as in maybe unused styles,.. are leaped in there

You should load any of the slow ones w/ devtools coverage on. It is not hopeful.

Yes, unused styles and code (for critical) have pretty high numbers which makes me have hope that we as a community could probably given these examples make tools.

The continual addition of more tools over the past decade has not meaningfully improved the fraction of code used nor interactivity nor site availability nor bundle sizes. Why is this time different?

The focus has shifted, it doesn't seem like we have aimed for the goals you are expressing for a long time. We also didn't have the right examples/problem scenario's for a long time or less publicly. I'd rather fight the problem than report it

Has the focus shifted? Admittedly a trailing indicator, but the rate of disasters crossing my desk has not slowed. And I hear more lipservice from the worst offenders than I observe concrete action.

I mean, Preact and Lit and Svelte et al are chugging along, doing the good work, and we very much need them. But I don't see the React community, e.g., actually making a turn & observe no real leadership from FB on this.

Do you have a ranked list of requests for React leadership? e.g. is your top wish to reduce the size of React itself? Or for CRA to do something? (What would you have it do, other than maybe failing production builds with large bundle sizes?)

For years I've been begging for: - guidance re: bundle sizes & mobile in their perf docs - movement on React size - public discussion of what it takes to keep perf in line at FB (pipeline, metrics, etc.) There's more, but that would show minimal interest in the problem.

Everything is constipated behind "concurrent will solve everything". I've seen one trace where it has made a difference, so it's not total vapor, but meanwhile the disaster count accumulates & picks up speed.
