One of the main reasons that you don't get a good post mortem is that it's often directly related to human error or a severe defect brought about by a decision to cut costs. There have been several huge outages in UK banking over the past few years and management have a convenient excuse in blaming "legacy systems". While I respect private enterprise, for systems of systemic importance I would like to see some legislation to implement a mandatory and detailed post mortem like you propose.
