I agree that it does not make sense from long term business perspective. But then what's left? I know for sure that my own payment information is gone and it coincided with AdSense system upgrade. Can anyone with AdSense account share if their payment information is still set? But even if it's just my payment information lost - it's not a good sign about quality of engineering at AdSense.
