Congrats/good luck on soon entering the workforce!
I think OP is a valuable contribution to an ongoing discussion, but I’d encourage you not to update too aggressively on any one post. There are good reasons that some of the most rigorous organizations in the space (CG) have made cage-free a top priority and ex ante you should think it unlikely that they all converged without good reasons– see e.g. @Vasco Grilo🔸’s comment above.
Adding to what Other Aidan said, I think it’s a mistake to think of the point on the spectrum from most to least helpful interventions where the real impact crosses from “very slightly helpful” to “very slightly harmful” as especially significant. If intervention A is worth 10,000 units, B is 1 unit, and C is −10 units, the difference between A and B matters much more than between B and C.
