AVP (Apple Vision Pro) w/ MacOS + BetterTouch Tool available (in AVP)?

The AVP can Connect To and display the MacOS screen.
The Apple Magic Keyboard provides a augmented reality of what you type within the AVP.

What stops the Apple MacBook Pro from displaying the Touch Bar within AVP?
Is this a feature / application that is possible to develop? If not, at a high level what is holding back?

I have been using the AVP since launch and wondered if this feature was even possible?
