This is the direction I hope that the FAA will take and mandate very firmly.
There was a very early post on this thread showing a photo of the NTSB examining the opposite side door plug on the incident aircraft, and the grounding of Max-9s and subsequently the 900NGs, was specifically so they could all be inspected thoroughly.
