That's one use case.

Another is when you really care about the exact sha1 (for example because you are an automated build system and this is the specific sha1 you have already decided you want to build).

Similar to the build system case I described above is when a human has a sha1 (from a mailing list, or source browser, or whatever) and wants to fetch just that revision, with --depth=1. You could use "git archive --remote", but (1) github doesn't support that and (2) that doesn't give you all the usual git-ish goodness.

Thanks and hope that helps, Jonathan
