We use the Python package setuptools-git-version for a variety of Python package automation steps and it runs git describe --tags --long --dirty in order to compare the HEAD commit with the most recent tag.

With checkout@v2's default to shallow clones (a default that I agree is sensible), this no longer works, and we have to set fetch-depth: 0. This works just fine, but it would be nice if there were an option to do a shallow clone of the HEAD commit and also fetch tags.

Thanks for considering.
