What about wrapping the defaultSD into the inner client and providing a method to close sd if necessary?

[HuSharp]

moved defaultSD into inner
I don't think it seems necessary to provide a function

• For default creation, there is no need for user to care about close sd
• For incoming sd creation, it should be left to the higher level to do the closing.
