Every contemporary vehicle which I have had to elevate had the body style shown in your images. The jack mechanism also matched the pinch weld for each vehicle. Additionally, for an electric vehicle which had to have the battery pack dropped, the lift points matched the design you've noted and the DIY method was indeed a hockey puck with an appropriately sized slot.

If you consider that you are spreading the load over a much larger area by using a wood block or hockey puck with a slit, the benefits compared to attempting a lift on a much smaller cross section pinch weld should be clear.

One could crush the pinch weld is the weight is excessive on the point of lift, while a spread-out force is less likely to do so, especially if the factory lift points are used, as they can be reinforced on the other side of the metal.

The jack stands are another complication, however. The slit hockey puck is going to take pressure from below in a less than spread-out manner, but certainly more spread out than the stand taking the load from the very edge of the rail-like underbody.

Consider also that once the vehicle is lifted, the jack stands can be placed on a suspension member or more substantial surface than the vehicle edges. This eliminates the worry of balancing the puck on a stand while lowering the vehicle to the stand.
