This is a question that I can't answer.
I am not sure why it isn't there. It might be that it is not practical to implement it on the client-side, or maybe they just didn't get a chance to write it yet.
With this last GWT release (1.4) there are a few new util classes that were added, and I am sure that will continue as time goes on. So it will probably be added eventually.
