+      handy for things like mail aliases (I want to list aliases rewritting things to bob). Without this projection table being available,
+      (ie we rely on schema version 6 or less) such information is obtained through a full table scan, unoptimized. From schema version 7,
+      the optimized projection can safely be used.</p>
