The user has requested a shutdown of the system, without saving their 
data first. How is it a bug that Emacs respects their wishes?

Here are the guidelines I was referring to:

http://windowssdk.msdn.microsoft.com/en-us/library/ms723653.aspx

    Applications that have unsaved data could save the data to a temporary
    location and restore it the next time the application starts, or simply
    respect the user's request to shut down the system even though it will
    cause data loss.

    If your application receives a shutdown notification while it is in the
    middle of an operation that should not be aborted, such as burning media
    or making a backup, it should display a dialog box. Warn the user what
    might happen if the operation is interrupted and enable the user to
    choose whether to cancel or continue the shutdown. If the user would
    like to cancel the shutdown, the application should return FALSE for
    this message.
    ...
    Applications should respond to this message as quickly as possible,
    saving time-consuming cleanup operations for the processing of the
    *WM_ENDSESSION* message.
