Yep. Renaming an account twice creates a mess, with tons of double redirects. Another reason they don't allow is to prevent people from doing it every other day. It doesn't work like a twitter handle. Tons of contributions have to be moved. Every time. When a staffer renamed their account, the site was slow for days.

One guy managed to do it, but by accident. first a regular rename and then another when the RenameTool was introduced. That wasn't supposed to happen, and now every wiki he's ever been to has his message wall in DoubleRedirects, and nobody has figured out a way to fix that.
