      1. What would you like to communicate to the user about this feature? 2. Would you like the user to see examples of the syntax and/or executable code and its output? 3. Which versions of the driver/connector does this apply to?

      So, given this code snippet:

      var bson = BsonDocument.parse(someDocumentToParse);
System.out.println(bson.toJson(JsonWriterSettings.builder()
                        .indent(true)
                        .outputMode(JsonMode.SHELL)
                .build()));

      The driver will generate a String that resembles to the mongosh syntax. To give you an example input/output:

      This:

      var bson = BsonDocument.parse("""
                {
                          _id: { $oid: "5735040085629ed4fa839473" },
                          code: { $code: "{}" },
                          n: { $numberInt: '10000' },
                          l: { $numberLong: '1355875200000' },
                          d: { $numberDouble: '10.5' },
                          dec: { $numberDecimal: '10.99' },
                          lena: 'olya'
                  }"""
        );

        System.out.println(bson.toJson(JsonWriterSettings.builder()
                        .indent(true)
                        .outputMode(JsonMode.SHELL)
                .build()));

      outputs:

      {
  "_id": ObjectId("5735040085629ed4fa839473"),
  "code": {
    "$code": "{}"
  },
  "n": 10000,
  "l": NumberLong("1355875200000"),
  "d": 10.5,
  "dec": NumberDecimal("10.99"),
  "lena": "olya"
}

      This is the behaviour of mongosh:

      mongosh test> EJSON.parse(`{
...                           "_id": { "$oid": "5735040085629ed4fa839473" },
...                           "code": { "$code": "{}" },
...                           "n": { "$numberInt": "10000" },
...                           "l": { "$numberLong": "1355875200000" },
...                           "d": { "$numberDouble": "10.5" },
...                           "dec": { "$numberDecimal": "10.99" },
...                           "lena": "olya"
...                   }`)
{
  _id: ObjectId('5735040085629ed4fa839473'),
  code: Code('{}'),
  n: 10000,
  l: 1355875200000,
  d: 10.5,
  dec: Decimal128('10.99'),
  lena: 'olya'
}
