From sujiezhu:

The current usage of loadRiskData() uses Bind() function which is not suggested to be used for now. https://cs.chromium.org/chromium/src/components/autofill/core/browser/credit_card_save_manager.cc?l=248-250&rcl=44e018e9a7c16a3d67ea9424b5afedf51a4559a9

I think it's listed as BindRepeating because it's required to be either BindOnce or BindRepeating, and its parent method is overridden by ~4 different callers:

We need to investigate why LoadRiskData needs BindRepeating and clean it up if we can change to BindOnce.
