Feature Request get a deserialized object from getJson

Hi, I'm trying to use Remote config services and wondered, why does getJson returns a string and not a deserialized object?
I noticed JsonConvert is already used to serialize in that class. why not create a - public T GetJson<T>(...)?

code from RuntimeConfig.cs:

Code (CSharp):

1.  
2.         /// <summary>
3.         /// Retrieves the string representation of the JSON value of a corresponding key from the remote service, if one exists.
4.         /// </summary>
5.         /// <param name="key">The key identifying the corresponding setting.</param>
6.         /// <param name="defaultValue">The default value to use if the specified key cannot be found or is unavailable.</param>
7.         /// <returns>A string representation of the JSON value of a corresponding key from the remote service, if one exists. If one does not exist, the defaultValue is returned ("{}" if none is supplied.)</returns>
8.         public string GetJson(string key, string defaultValue = "{}")
9.         {
10.             try
11.             {
12.                 return _config[key].ToString();
13.             }
14.             catch
15.             {
16.                 return defaultValue;
17.             }
18.         }
