Pretty much, they magnet together though so you can split them apart and use them as normal with other devices.

It would make since to say something like usb-c is required for up to x volts. Then x-y volts require this other kind of charger.

I mean it’s totally valid if the required technology literally can’t handle certain applications that there needs to a level 2, level 3, and onward option.

There are already laptops with docking stations that take 2 USB-C connectors. Annoyingly, the docking stations come with a Franken-connector of 2 USB-C plugs in one solid plastic housing so you can only use the dock with a specific laptop.
