Even in git, amending doesn’t rewrite the actual commit though. It creates a new one. You can find the old in your reflog. Think about it, the commit hash is based on the contents, so it must be changed on any content changes. It’s only after pushing that history is written in stone. So you can say git never removes anything either. The biggest issues with data loss in git is before you have done a commit. There, many actions can nuke your changes because you mixed up two flags, trying to rebase before commiting, etc. As long as you have a commit though, the reflog will save you from failed rebases.
