My understanding is Quest 2 can run Rift games using the optional link cable. But I'm not sure if that means it will take advantage of higher resolution on Quest 2 or whether X-Plane devs have to do something new.
What is irrelevant is if Quest runs with X-Plane or not, even if it doesn't.
The original subject of this thread was if VR is a gimmick or not. I initially replied that yeah, for some it's a gimmick and for others there is really no alternative. Now we're plenty off topic here :)
