I've generally had no gripes about this or web vitals in general except for one thing: group population[0]. It's unfair to create a blast radius on a small or medium-sized business's website simply because enough data doesn't exist to determine the true extent of the user experience impact.

The most recent example I've observed this on was a website with a heavy interactive location finder experience that lived on a single page. Fine, penalize that page. There's a chance users won't initially navigate there anyway. However, because a (very minimal, practically irrelevant amount of) similar content on the rest of the page was present on 18 other pages, the impact was huge.

The reality of the web today makes this pretty dire in my mind. Many businesses choose to run websites that are generally fast, but they have to engage with third-party services because they don't have the means to build their own map, event scheduler, or form experience. The punishment doesn't fit the crime.
