The pinchweld is supposed to support the weight of the car, not the area around it according to this.

I see, thanks for the info Allez, it seems they do say the bottom of the pinch weld is what supports the car's weight. My ZL1 Addons lift pads do appear to butt against the floor, but I think the bottom of the slot is also in contact with the edge of the pinch weld, at least they are extremely close to the frame at both locations.

This pinch weld is one of those unintuitive designs that may be mechanically sound, but will keep confusing everyone to no end, because a few thin sheet metal edges will never appear sturdy enough to hold up 3600-4000 pounds without bending, welded high strength steel or not.
