I'm thinking the would tend to put less. The amount of pull is indexed, you get to the end, you're out of clicks, and you're not putting as much stress as a ham fisted operator of a friction shifter.
Perhaps the cable routing and the associated bend could put more stress on the cables than down tube shifting.
In my experience broken cable seemed a lot more common 30 years ago than today.
