I think what Mercurial brings here is that even if you have a repo and you do a force-push you keep all the heads. Thus it's almost like a history of changes.

I think what Mercurial brings here is that even if you have a repo and you do a force-push you keep all the heads. Thus it's almost like a history of changes. I think if you do a code-review and you get the final state of the repo to check, you can nicely tell how it was evolved/squashed/re-ordered. I find that workflow much more useful than just rewriting history like in git (i know about reflog)
