Bill Schneider updated SPARK-56561:
-----------------------------------
    Description: 
It would be good for reference documentation of SQL functions to explicitly say 
when functions like `array_distinct` will (and won't) preserve order.

This would be useful to cite during code reviews, and may also help inform AI 
coding agents.

This might also apply to `array_intersect`.
