I am executing a Convex hull algorithm on the 3D space of "dt-bindings maintainer opinions" to get a convex hull of acceptable dt-bindings choices where two different choices are functionally equivalent. With this additional opinion on the krzk axis, I now know that having the base properties accurate for the general case is not required if the per-compatible case sets the property to false anyway. I hope no two opinions are collinear, as this would surely be my undoing. You get to pick which axis (X, Y, Z) you are. Right-hand rule, of course. Kind regards, Nicolas Frattaroli
