Google: We Don't Announce Deprecating Ranking Signals

Has there been a time where Google has said they no longer use a specific ranking signal? I mean, they said this like 20 years ago with maybe the meta keywords tag? Google said this with rel next/prev, Google News stock tickers and keywords, and some other things. But generally, it is rare to see Google say we no longer use X as a ranking signal.
