The reason this hasn't happened to any wider degree is quarterly capitalism and institutional inertia.

Even if you bring a new CEO in that has these ideas, the org chart will fight it with tooth and nail as managers would lose reportees and clout.
Consultancies in particular are incredibly inefficient by design since they make more money if they take more time and bring a larger headcount to the task: They don't sell productivity, but man hours. Hence horrors like SAFe.
