Consider the setup process for the Apple TV. The TV shows a unique one-time-use QR code-like pattern that you can scan with the camera of an iOS device. Surely something like this would be sufficient for pairing a Vision Pro with a Mac.

Also the security implications of encouraging people to add their personal Apple ID to devices they don’t own are, IMO, worse.

I'm being more cynical and assuming it's probably to do with AirPlay screen-mirroring encryption and how tying everything to the same Apple ID account placates Hollywood's technophobic licensing execs.

I think it’s a lot simpler than that. If they require both devices are logged in to the same account, they don’t need to deal with authorization. You would not believe how much development time this saves.

Except that you can have a different AppleID for your system versus content.

This is an incredible point that I had not considered.
