I do use the `git worktree add --no-checkout` trick in one of my scripts to have a "super light-weight" worktree. To make it work in your case, you'd then have to inspect the changes you want to replay, e.g. via `git log --name-only <range>` to craft an appropriate `sparse-checkout` file (but don't forget to *also* set the config variable `core.sparseCheckout`) before checking out any files. I am sure you can even automate generating that `sparse-checkout`. > Would the partial clone feature added in v2.19 be helpful here? I doubt it. The partial clone still needs you to know which files you want. VFS for Git would help you here. But something tells me that you're on Linux, and there is no official VFS for Git on Linux yet.
