I would then expect people to complain "why is this one without cockpit etc". For a released game, it makes more sense to release a complete plane one at a time.
Early Access on the other hand...
I'd love to have VR support for Tiny Combat Arena but that's just another pile of tasks to do - the easiest setup would be use menu system as is but just render it on a plane in 3d + replace mouse with a controller, just one (BTW drag'n'drop using two controllers is a nice feature, rarely used, but when it comes to coding it's a land of adventures). And with virtual cocpkit it may be actually even easier to make it work.
But that might be at least a couple of weeks of work. And if it would be ported to Quest... It may make more sense to even start to think about it, long time after the initial release.
