I don’t get why backward compatibility is even expected, other than a nice-to-have. Historically, gamepads weren’t portable between generations of systems.

I’ve got a Logitech steering wheel that I can’t use on 64-bit Windows because of the way the driver was implemented.

Because we all know that under the covers it's just Bluetooth and USB, and they don't have a good reason. Especially in Xbox world, where while the hardware on an Xbox Series X is more powerful than an Xbox One, the software is largely the same.

Nitpick: Xbox One controllers communicate using a proprietary WiFi Direct protocol. Bluetooth is only there for pairing with other devices.
