This was introduced but never really used outside of core[1]. The only place that used it in core was MainStash setting which under the hood will use CACHE_DB (SqlBagOStuff). This patch removes the "db-replicated" key in $wgObjectCaches without deprecation because it was never really used in the first place and had a replacement already when it got released, see: T352481.
