I noticed the same for Google's site https://web.dev/

The last article pushed to the feed was "Changes to the web.dev infrastructure" few months ago https://web.dev/blog/webdev-migration

The feed still there but with no updates https://web.dev/feed.xml and on the site you can see new articles published.

Is sad that on a infrastructure revamp of a modern site, the RSS feed was left out of the features list (at least for now).
