-  title: Remove DOC_VALUES_SKIPPER feature flag
+  title: Enable doc_values skippers
   body: |-
-    Removing this flag will enable skippers automatically on keyword, ip,
-    boolean,     date and numeric fields that have index=false and
-    doc_values=true.  In addition,  some fields in time_series and logsdb
-    modes will default to using doc values  skippers in place of points or
-    terms indexes.
+    Doc_values skippers add a sparse index to doc_values fields, allowing efficient
+    querying and filtering on a field without having to build a separate BKD or terms 
+    index.  These are now enabled automatically on any field configured with
+    index=false and doc_values=true.
+
+    TSDB indexes now default to using skippers in place of indexes for their 
+    @timestamp and _tsid fields, greatly reducing their on-disk footprint.  
+    LogsDB indexes default to using skippers in places of indexes for their 
+    @timestamp and host.name fields.
