This seems too restrictive and is not "obvious" to me: I currently use git-new-workdir to have multiple checkouts of the same branch, with no ill effect. While those who do not understand what is going on underneath might be confused by one checkout suddenly showing uncommitted diffs, I don't accept that as a reason to outright prevent such use. I suggest, at the very least, that this behavior be overridden by a --force flag?
