This material is concerning to me on a base level.

To me, it doesn't reflect positively on the cost and complexity to implement a large scale system. It presents much of the material without a simple guide to what should be optional, when, and where.

You almost need a huge number of people to even digest the material and then make decisions about it. It feels like a massive reflection of the government contracting industry. I see it illustrating the value of editorial or architectural control and a willingness to take risks by saying "no".
