The “BAE safety report” is an authoritative document, commissioned by the IPT. They contract the Aircraft Design Authority to be aware of the complete picture, and distill it down to key issues – in this case safety hazards and risks – so that they (the IPT, in consultation with stakeholders) can make informed decisions.
The aim (presumably) is to take a proactive approach to risk management, rather than reactive. Put another way; try to prevent accidents, rather than waiting for one and the subsequent BoI report, before taking action. I sincerely hope the BoI report doesn’t recommend actions which have been already recommended in the BAeS and QQ reports mentioned here, but were not implemented.
I think the point that has been made here and in other threads, on numerous occasions, is that BoI reports often present recommendations as their own exclusive ideas, conveniently omitting that they have been made many times before.
