> The change for non-AMP content to become eligible to appear in the mobile Top Stories feature in Search will also roll out in May 2021. Any page that meets the Google News content policies will be eligible and we will prioritize pages with great page experience, whether implemented using AMP or any other web technology, as we rank the results.
> In addition to the timing updates described above, we plan to test a visual indicator that highlights pages in search results that have great page experience.
Seems like a positive change. It will mean extra work as developers improve the performance of their sites. But having clear metrics to improve will make that work tractable. Also, advocating for that work to senior management will be easier when it's so clearly tied to SEO.
The upshot is that ordinary users will experience a more performant web. Not overnight but over a few years, like the shift to HTTPS and supporting mobile web versions. Both of those changes were driven in part by the desire for better ranking on Google.
