I don't see how that helps more than marginally.

Doesn't PCI require a payment processor to keep some amount of the transaction data for a specific period of time?

Personally, I love tokenized transactions / specialized payment processors (eg Apple Pay, Stripe, PayPal) because they actively work to keep most of the data away from etailers (who are generally not specialists in securing their checkout flow). The problem is the payment processor transaction fees can be steep (2.x% for most commodity CC processors all the way up to 15% for Apple Pay), so etailers lose on the margins and avoid the more secure options.
