As I wrote this a while ago, before reflogs and packed refs, and I only needed it for the initial conversion, it only had to write out new commit objects and retarget branch heads and simple tags. If cg-admin-rewrite-hist can do better and can be merged into git-core I would say that is a win-win situation for everyone. Something like this should be available to allow people to reconstruct their merge history or fix up empty 'file was added on branch foo' commits that are left around after the initial import from another VCS. Personally, I don't think it should ever be used for any published repositories or branches. Most fixups before publishing can already be done by rebasing or amending a commit, so this would only be useful for that intial import where there are in fact a lot of scattered changes all over the place, or to reconstruct a merge that went bad. But really in that case, it is probably better to redo the merge correctly and rebase any commits that might have gone in after the bad merge.
