There's a reason why everyone else uses thicker cables and strain relief.
And it's not because of end-user negligence: it's because of engineering pragmatism.
Although all this is irrelevant since Apple phased out mag safe, the "ears" that hold the cable, and added a removable cable.
Still, Apple's Lightning cables are also extremely vulnerable to bending and abrasion. What makes you think their USB-C cables will be much better?
Non-technical customers who can't afford to buy new cables, or don't know to use better aftermarket cables, are already known to resort to using springs from pens as ad-hoc strain relief: https://www.google.ca/search?q=iphone+charger+spring
Nothing, but at least those can be replaced without having to upgrade the whole power brick.
