> Often, a multivalued field is used as a set of values. Since multivalued fields are more like lists than sets, users do two consecutive operations, remove and add, to insert an element into the field and also maintain the set's property of only having unique elements.
> Proposing a new single operation, called "add-distinct" (which essentially means "add-if-doesn't exist") for this.
