I think the ScopedConnection is a wrapper for a Connection instance.
So it can return the status of the Connection instance (true or false for isConnected function).
However, if the ScopedConnection is released, then there is no Connection instance, does it mean just return false when someone call the isConnected function?

A ScopedConnection without a Connection should return false for isConnected().
