   > I wonder if it's better to try centralize ambiguity checks somewhere, instead of trying to hunt down the different places that can resolve columns and implementing the checks there. Like a new analysis rule to resolve column references, though would require changes to planner (large impact?).
   
   Yes, I think consolidating the ambiguity checks and resolving column references (where they can be more easily documented and unit tested) would be very valuable and help DataFusion along
