      Steps to reproduce with mongo_crypt:

      Build the "csfle-markup" tool. It is a tool in libmongocrypt to mark up commands with the mongo_crypt shared library.

      % git clone https://github.com/mongodb/libmongocrypt.git libmongocrypt-explain-with-apiVersion
% cd libmongocrypt-explain-with-apiVersion
% cmake .
% cmake --build . --target csfle-markup

      Mark the explain-with-apiVersion.json through csfle-markup:

      % cat ../explain-with-apiVersion.json | ./csfle-markup ~/bin/crypt_shared-6.0.0/lib/mongo_crypt_v1.dylib | jq .
Loaded csfle library [/Users/kevin.albertson/bin/crypt_shared-6.0.0/lib/mongo_crypt_v1.dylib]: mongo_crypt_v1-dev-6.0.0
{
  "hasEncryptionPlaceholders": false,
  "schemaRequiresEncryption": false,
  "result": {
    "explain": {
      "find": "default",
      "filter": {}
    },
    "verbosity": "allPlansExecution"
  }
}

      The "apiVersion", "apiStrict", and "apiDeprecationErrors" fields do not appear to be returned in the results of mongocryptd or the mongo_crypt shared library.

      mongocryptd omits "apiStrict" or "apiDeprecationErrors".

      mongo_crypt omits "apiVersion", "apiStrict" or "apiDeprecationErrors".

      For example, marking up the following with mongo_crypt:

      {
    "explain": {
        "find": "default",
        "filter": {},
        "$db": "db"
    },
    "$db": "db",
    "apiVersion": "1",
    "apiStrict": "true",
    "apiDeprecationErrors": true,
    "jsonSchema": {},
    "isRemoteSchema": false
}

      Results in this output:

      {
    "hasEncryptionPlaceholders": false,
    "schemaRequiresEncryption": false,
    "result": {
        "explain": {
        "find": "default",
        "filter": {}
        },
        "verbosity": "allPlansExecution"
    }
}

      "apiVersion", "apiStrict", and "apiDeprecationErrors" is expected in the output.

      The output is the same for version mongo_crypt_v1-dev-6.2.0-alpha-336-ga7ba740.

      Marking an explain command with mongocryptd does not appear to preserve "apiStrict" or "apiDeprecationErrors" in the output.

      // Run against mongocryptd with: mongo --port 27020 explain-with-apiVersion.js
var cmd = {
    "explain": {
        "find": "default",
        "filter": {}
    },
    "apiVersion": "1",
    "apiStrict": false,
    "apiDeprecationErrors": false,
    "jsonSchema": {},
    "isRemoteSchema": false
}

var got = db.runCommand(cmd)
printjson(got)

/*
Prints:

{
        "hasEncryptionPlaceholders" : false,
        "schemaRequiresEncryption" : false,
        "result" : {
                "explain" : {
                        "find" : "default",
                        "filter" : {

                        }
                },
                "verbosity" : "allPlansExecution",
                "apiVersion" : "1"
        },
        "ok" : 1
}
*/

      The output is the same for version 6.1.0-alpha-986-g960265d
