What is the main purpose of WebExceptionStatus.Success?

I am a little confused about the purpose of the enum value Success of the WebExceptionStatus enumeration. I did a search and couldn't find that this enum is used outside of the WebException class. This confuses me very much. Why should exception be used to indicate successful action / status. Am I missing something, or have I not searched enough? Has it been submitted for future features?

Please, if anyone knows their main purpose, I would be grateful if he / she could share an explanation with us.
