My main issue with Git, other than the terrible UX of the CLI, is just how common it is for one to want to rewrite the commit history - an operation for which there's no version control.
You better get it right, or otherwise you get to nuke the whole repository.
You might be interested in my project git-branchless https://github.com/arxanas/git-branchless or the Git-compatible Jujutsu SCM https://github.com/martinvonz/jj, both of which have version control for commit history via an operation log. Both feature sensible `undo` commands.
