Odd, the number of pins is the same, as well as the basic pin design.
I've wondered for some time of the "stretching" of chains was actually occurring in the chain plates rather than at the pins, especially in multi-speed bikes.
So, I could imagine the shaped half-link plates would be at greater risk for stretching.
