Opt-out of JTokenType.Guid (and other "custom" JTokenTypes)

Source/destination types

public record Example(Guid Id);

Source/destination JSON

{ "Id": "e4729b1e-3f1f-4386-b5c7-2a828280f8f0" }

Expected behavior

JObject.FromObject(x) acts as a "shortcut" to JObject.Parse(JsonConvert.SerializeObject(x)). If it doesn't act like such a shortcut by default, a flag could be passed to the serializer for JObject.FromObject to enable behaviour that makes it a shortcut to serializing to string, then parsing again.

Actual behavior

JObject.FromObject embeds additional metadata into the values, like JTokenType.Guid, JTokenType.Date, etc. This creates a difference in behaviour between JObject.FromObject and using JObject.Parse on a previously serialized version of the same object. This is very frustrating when having to write code that has to deal with JObject instances from both sources.

Steps to reproduce

public record Example(Guid Id);

public class Program {
    public static void Main(string[] args) {
        var example = new Example(Guid.NewGuid());

        // Convert to string and parse that
        var exampleJsonFromParsedString = JObject.Parse(JsonConvert.SerializeObject(example));
        var exampleIdFromParsedString = exampleJsonFromParsedString.Value<string>("Id");
        Console.Out.WriteLine("exampleIdFromParsedString = {0}", exampleIdFromParsedString);

        // Convert to JObject directly
        var exampleJsonFromObject = JObject.FromObject(example);
        var exampleIdFromObject = exampleJsonFromObject.Value<string>("Id");
        Console.Out.WriteLine("exampleIdFromObject = {0}", exampleIdFromObject);
    }
}
