USB-A is only rated for 1,500 mating cycles, whereas USB-C is supposed to last for 10,000... Though in reality the ports on my phones seem to start getting too loose to hold the jack in at around 1,000 cycles. Still, it's not a totally unreasonable standard, and any device that hasn't been designed to be thrown away should have ports broken out onto replaceable subassemblies -- as is the case with many business-class laptops, for instance -- so replacing a failed USB-PD port shouldn't be too much trouble.
