USB-C for laptop chargers isn't a fantastic idea IMO. The majority of laptop manufacturers solder USB-C ports to the motherboard, so when the port inevitably wears out/becomes loose, you need to have micro soldering skills to replace it. Putting the USB-C port on a daughterboard (or flex cable as seen in phones) isn't easy to do if you want to push USB 4 speeds through the port (40 Gbit/s).

Compare that with the traditional barrel connector which is usually an easy repair. Most designs have the barrel connector on a cable assembly rather than having the connector soldered to the motherboard.
