Right, but the tree hash does not directly allow to see which objects
are tracked or not.  This information is necessary to reconstruct the
signed tree.  (Having tracked files first, then the signature file and
then untracked files in the archive would be an easy way to transmit
it.)

git archive uses convert_to_working_tree() to archive the same file
contents as tar or zip would.
