With respect I think that you're missing the point of Rody's advice on what constitutes a safe and quality repair.
Sure you could add extra inserts, pins, plates, gussets, welds and whatever else to make the frame virtually indestructible, but at the same time you could double it's weight and kill any ride characteristics.
There is a big difference between aircraft engineering and bicycle engineering, and while I wouldn't doubt the skills, experience and knowledge of an expert in that specific area, I would also hesitate to undermine the input of somebody as skilled, experienced and knowledgeable as Rody is in his.
