It's unlikely they'll do it, though. I've only seen one double rename, and you should see the mess that gave. There's still double Message Walls redirects on wikis that I'm told even staff doesn't know how to get rid of.

The story I heard was that that one time may have been an oversight, a result of the UserRenameTool. It's definitely not something they want for everyone.
