   > For SparkPlan nodes that lack a logicalLink (e.g., SortExec / 
BroadcastExchange generated by EnsureRequirements), GlutenFallbackReporter 
cannot copy their FallbackTag onto a logical plan,
   
   Just curious, does this behavior differ across Spark versions? I checked 
latest Spark code and the rule adopts `transformUp` which should've copied 
logical links to the sort / exchange nodes:
