P.S. There are a LOT of details in this specific idea, some consumers are bad actors and are never happy, some merchants likewise are bad actors. Resolving these issues without disclosing sensitive information is extremely difficult. But largely processors are sort of punting on it in various ways when common sense resolutions seem possible. Like if a consumer has 50k transactions with 0 chargebacks and they initiate a chargeback, it's probably a merchant problem. This argues for collapsing the layers but channel-specific resolutions have the advantage of being able to look for delivery signals and other specific mechanisms of performance. Figuring who is right in the world is a hard problem in general. Possibly the Stripe Elite will correct me here since this is the Hard Problem of payments. Which can be solved well enough with statistics. Payments has a whole lot of Hard Problems which seem easy at first, it's a great area.
