Thanks.
That would require some major respecification of PSTN calling standards.
That said, yes, something along these lines seems necessary.
Even automated curtailment by last-link telcos (e.g., your own telco) based on rejection / complaint rates (e.g., recpients reporting calls as spam) could be A Thing, and are not dissimilar to how email spam management occurs today. Making that the peer's problem incentivises them to clean up their acts.
As an aside: you could then easily add carriers or intermediaries to a block list. You could even subscribe to a distributed block list. You could subscribe to an always-allow list that contains hospitals, police stations, and emergency services. It'd be so much better than what we have now.
