Per vertical lines of defense

What if … Lines of Defense aren’t three (or four or five) ‘horizontally’, but vertical, like actual protection against things getting out of bounds ..?
Wouldn’t that return the whole concept of 3LD, TLD, Three LoD or what’s your favourite abbreviation, to the already tried and tested process control models of yesteryear and when not if Yes, wouldn’t you be found out to be a sort of bumbling eager beaver when you think you’re still doing great and are Really Important and a GRC star and don’t see your kindergarten Importance is called out to hang high ..?

Because then, you’ll need no more big Risk departments with all the procedural justice, compliance on paper (and actual (operating) effectiveness nowhere!), etc., just some nimble support structure. Then, a major part of the conzulting industry would collapse and core management capabilities would have to be returned to formal and practical education and experience-training.

Oh well, one can dream, can’t one?
