Changing of archive packages to git tags

Ey, Recently, a bunch of packages such as cowsay have switched to pulling from a git tag away from downloading from the /archive/ path of GitHub. Since downloading GitHub's archives are guaranteed to have the exact same contents as pulling from the tags, with the added benefit of not pulling the .git folder, is there any benefit to this? To my knowledge, the problematic xz tarballs were under the /release/ path as uploaded artifacts, while the /archive/ download remained clean. Aaron
