That’s right afaik. When I ordered my iPhone 13 I knew about the special Series 7 Charging cable. I ended up buying a stand where you can/have to put the MagSafe charger and the watch charger in yourself. There are also options that let you add a Lightning cable for wired AirPods Charging, sadly I haven’t found one with an added wireless charging pad.
Anyways. Of course you’ll need separate charging bricks or bricks with multiple usb-c ports but it works for me. Also it cost only 28€, so even when adding the MagSafe charger and a 2x20 Watt USB-C PD Brick you end up comfortably below most other options…
