It isn't just Airbus working over there on this stuff, Dassault is moving forward with this on the Falcon 10X.
Dassault is anticipating a potential need for reduced crew operations, which could be one pilot flying while the other rests and only two pilots flying long-range trips. Thus, the flight deck design reflects this concept, with the pilot seats able to be fully reclined to facilitate extended minimum crew operations, allowing one pilot to sleep in place while the other operates the aircraft. This would be allowed only above FL200, and Dassault has already begun discussions with regulators on how this capability can be certified.
Dassault's Falcon 10X has many new features, including composite wings, a T-tail, touchscreen avionics, Smart Throttle, and Rolls-Royce Pearl engines.

That being said my Part 91 job I flew both Falcons and a King Air 350 and while my BE300 type rating is unrestricted (single pilot) we never operated it that way. And they continue to fly their PC-24 in a similar fashion, single pilot type ratings flown as a crew. The thing to watch out for in those type of jobs is while that is the rule now, all it takes is a change in leadership and that will end whatever protections you thought you had.
I feel much better protected with my union and PAC looking after me than what I had under part 91.
