Deleting work item in TFS 2010

After the release of TFS 2010 power tools I have noticed that the command destroywi that is used for deleting work items was removed. Searching the Visual Studio installation directory I found a new command line utility called witadmin.exe. This new tool hosts all the known work item management commands like import, export... To delete work items you use the same command as in the power tools with the work items id as a parameter:
Example: witadmin destroywi 10
