Wow. I think the folks who would use the mod you mention would very much be in a minority.
I dont see AI-controlled companions as anything but a complete disaster. They would inevitably (and I suspect not infrequently) do something completely the opposite of what they should do. Picking their spells etc on level‐up? How could one plan synergies between abilities if you can't be sure the relevant abilities would be used synergistically?
