I have some friends with the same model of bike or a competitor bike Specialized, Giant, Cannondale...same-same...no issues with their shifter cables and many many miles on their bikes. Just checked with the girl....~3500 miles on her Domane and it still shifts fine and no cable problems.
Maybe there was certain run of shifters in the past that this was a problem and it was addressed on newer models? A quick google search indicates this inherent issue you describe was on Shimano 5700 series shifters. My bike and her bike have Shimano 105 R7025 and R7020 shifters.
