Fulfilling a request of the editor I try to put the aforementioned paper into perspective of relevant results obtained before. In particular I point out that supersymmetry of the S‐operator in cases where it exists is not necessarily in danger. Local couplings reveal however that some composite operators undergo a breaking of their supercovariance, a fact which has been established by Elisabeth Kraus.
