Relation status was introduced in https://github.com/juju/juju/commit/fe60b166756826fc982762c1dee84e272a252483, as part of the CMR work.
In State.Relation.SetStatus, there's an assumption that a relation already has a status: https://github.com/juju/juju/blob/2.3/state/relation.go#L125. No upgrade step was written to set a status for existing relations.
