I was under the impression that the relevant logicians (e.g. Anderson, Belnap, Dunn, Meyer) had solved this problem (of having to avoid irrelevant contradictions) decisively. Instead, EY uses the gadgetry of surgery on causal Bayesian networks to address this. Is there a sense in which relevant logics are doing screening and/or surgery? Does anyone know of an exposition that connects relevant logics to Pearl's counterfactuals?
