You’re right for low-power devices up to 5V/2.4A, to a point. All those USB-A to C chargers/cables didn’t stop working; they should be replaced through normal attrition to the new standard rather than replaced wholesale. I know I still have a bunch I’m using and will continue to until they’re kaput.
But PD capability via USB-C is a game changer. I’ve been in day-long meetings with people who just swapped one charger between at least three different brands of laptops/tablets. Now you don’t need think anymore about which I adapter you have, you just plug it in and it charges.
