I think you're making exactly the same point. It's not a model to follow because it was a way of working that fit their requirements at that point in time. Given a different company, project, team, ecosystem, etc, the decision may well be different. Thus, you shouldn't follow their model unless you are identical in every way. What you should follow is the way they arrived at a decision, not the decision itself.
