Maybe this was covered in a previous round, this series is a little hard to follow since each version isn't In-Reply-To the version before it, but why is this option needed, i.e. why would you do:

    git commit-graph write --object-dir=/some/path/.git/objects

As opposed to just pigging-backing on what we already have with both of:

    git --git-dir=/some/path/.git commit-graph write
    git -C /some/path commit-graph write

Is there some use-case where you have *just* the objects dir and not the rest of the .git folder?
