+	//   is interpreted as "data at least as new as the provided `resourceVersion`"
+	//   and the bookmark event is send when the state is synced
+	//   to a `resourceVersion` at least as fresh as the one provided by the ListOptions.
+	//   If `resourceVersion` is unset, this is interpreted as "consistent read" and the
+	//   bookmark event is send when the state is synced at least to the moment
+	//   when request started being processed.
+	// - `resourceVersionMatch` set to any other value or unset
