Yeah, there's a lot of obviously wrong data that could be caught be something pretty simple here. The trouble is there's no hard rule, neither kind of entry implies the other. See #7545.

Some kind of grouping concept would be useful I think, where the expectation is that data should match but there's a way to make it not match if that's really what happened.

Running mdn-bcd-collector doesn't update the onpaymentmethodchange entry this is based on, so it's probably mostly right.
