This seems wrong, since you can't push transactionally + consistently in S3.

They address this directly in their section on concurrent writes: https://github.com/awslabs/git-remote-s3?tab=readme-ov-file#...

And in their design: https://github.com/awslabs/git-remote-s3?tab=readme-ov-file#...

But it seems like this is just the wrong tool for the job (hosting git repos).
