Page experience, page speed, etc. were just miscategorized, as they are not ranking systems, they are signals. They should have never been listed as systems to begin with. Google simply cleaned that up. In Google's precise words: Ranking *systems* are different than ranking *signals* (systems typically make use of signals). We had some things listed on that page relating to page experience as "systems" that were actually signals. They shouldn't have been on the page about systems. Taking them off didn't mean we no longer consider aspects of page experience. It just meant these weren't ranking *systems* but instead signals used by other systems.
