REVISION SUMMARY The end goal is to have changesets centric sidedata information stored into changelog sidedata. This make it possible to use the changeset based copy tracing algorithm on any repository without affecting hashes. The actual implementation is coming. The feature is marked as experimental (do not use in production) until we stabilise details about the format.
