      SERVER-79411 created the InsertionOrderedColumnMap class, which stores keys in insertion order. This is because DocDiff generation for a bucket iterates the before/after objects in lockstep. If DocDiff application has no restrictions on field name ordering in the diff, we can simplify this map class. We should also see if maintaining the same field name ordering across diffs brings any performance benefits
