I'd like clarification on a detail here. Is it only about not adding any new commits, or about keeping all existing commits as well? IOW, do you want to: - include only commits already existing in the commit-graph, without adding any new commits, but remove any commits that do not exist in the object database anymore. or: - include _all_ commits already existing in the commit-graph, even those that don't exist anymore in the object database, without adding any new commits.
