Hm, so it's a cache then? Requesting the same tarball 100 times shouldn't create 100 zip files if they're cached, and if they aren't cached they shouldn't fill up the disk.
They are a cache, but you can generate them for each branch, tag, and commit in at least three different formats... Now imagine you have a repo with several thousand commits.
Yeah, fair point. Although I think the only uniqueness is commits here, tarballs generated from branches and tags are ultimately the same as the ones generated by the commit that those reference. But I still agree with your overall point.
