   > I don't like the idea of `SemiJoinRule`, which is counter intuitive. A boolean context IN or existential subquery should be decorrelated directly into SEMI/ANTI SEMI join, rather than transforming to Join/Outer Join, then to SEMI/ANTI join.
   
   I'm +1 on this idea, we may need some refactoring for the RelDecorrelator.
