 Review comment:
   XCOM feature if not used should be disabled by default as in base operators, users should
declare explicitly the use of XCOM so that database is not filled with useless data.
   
   For backwards compatibility, contrib operators, which currently push to XCOM by default,
 should be updated to activate XCOM explicitly, doing this way, other contrib operators will
keep the current behavior of not using XCOM.
