Why a content-addressable blob rather than just a directory with entries named after the SHA (which you can later tar up if desired)?

That would work as well. I'm not sure if extraction of a file by filename from a compressed tarball is particularly efficient or not.

Ahh I see. If fast random access is a requirement that makes things a bit more tricky, yes.
