Totally fair. The intended argument is that downloading (and parsing and executing) an entire page just for one button click to load is slow.

But if you can hydrate granularity, and prefetch smartly (based on visibility, analytics, etc) things speed up a lot.

If done right, there is no delay on interaction, and a lot less time and resources required to load a page, increasing lighthouse scores and TI specifically

Thats what we’ve seen in the field too, the FAQs in the article link to some real world examples. Tho I can’t say our prefetching is as smart yet in practice as we want, so sometimes there is a delay on very first interaction. There is a straightforward way to improve this tho that we are working on
