As another thinking out loud idea, I was wondering if the graphite team have considered storing the

parentBranchRevision

ids directly in a ref (e.g.

.git/refs/branch-metadata/my-branch/parent-base

instead of a json file so that it could integrate with the

--update-refs

feature that's in Git 2.39, so then if people where to use

git rebase --update-refs

(or if they enable updateRefs globally) that could be compatible with graphite?
