Definitely want this. We work on a purely centralised setup with no local repositories.

It's too difficult to train our non technical staff to handle local repos and merging in.

I accidentally forgot to put in a checkin comment when I checked in a new branch, I also forgot to checkin "added" files.

Now I have one changeset that has no comment and another that just checks in needed files. I need to delete both of these (without updating my workspace), then check them into a new branch.
