      To support the use case of encoding Go structs as MongoDB documents, we will add an omitnil BSON struct tag that only omits nil values but includes empty values. The $push and $addToSet update operators work the same when modifying document fields that are empty arrays and document fields that do not exist (the only problem is document fields that are BSON null), so the behavior of omitnil maps well to that use case. Additionally, other MongoDB drivers (e.g. Java and Rust) offer a similar behaviors.

      Definition of done:

      • Add an omitnil BSON struct tag that only omits nil values but includes empty values.
