I am not denying that it could have been a factor here (although all based upon speculation), and have already acknowledged that indeed it should not distract from flying the aircraft, as nothing should.
When the policy of wing deicing got changed (deice contantly ON when there is ice buildup) the reason for the wing inspection light disappeared
This implies to me that it is being considered not necessary to monitor the build of ice on the airframe if you have your de-ice systems turned on.
THIS I find rather bemusing and concerning.
