They could have replaced the USB-A to Lighting cable and charger they ship with iPhones for USB-C to Lightning years ago.
(Personally I’d like to see Lightning replaced too but that’s a different story).
[EDIT] go figure, my wife just today bought a new iphone, wants to put some music from her 2019 Macbook Air onto it, needs to plug it in at least once in order to do that (have to plug in first to enable wifi sync), and can't because the phone shipped with a fucking USB-A cable and the single lightning-to-usb cable we have in our house is missing. This is going down right now. So much for not needing USB-A ports on a laptop in 2020 even if you're fully in the Apple ecosystem. She's so annoyed I wouldn't be surprised if she returns the phone. I mean granted the phone isn't the latest model but it came out way after they made the all-USB-C switch on their laptops.
Hell, to this day the only actual USB-C devices I've seen in person are Apple peripherals and monitors catering to Macbook users, which almost all include other ports anyway. I'd add Android phones but those mostly have USB-A connectors on the other end of the cable (like the iPhones that were shipping for a while after the USB-C Macbooks came out—there's another giant WTF). USB-C market for flash drives seems to suck (form factor's worse, price is higher).
[EDIT] oh and when the new port is intended to replace all other ports the half-life on "legacy" devices for me probably goes from ~10 years to ~20. Seriously. WTF Apple.
