I'm not convinced that the two failures had the same cause. The symptoms are different (apparently one PMIC, one SOC), which may or may not have a common cause. That, of course, says nothing about whether the cause is design, manufacturing or environmental. We do know that there were common environmental factors (including a non-standard PSU), and of course the design hasn't changed significantly. It does seem unlikely that the two were from the same batch, but that can't b proved without serial numbers for both Pi.
