From a development time standpoint, it's not feasible.
They'd be dedicating many hours of valuable dev time into a VR experience that can only be experienced by those with an iron gut. A subniche of an already tiny niche.
I have thousands of hours in VR and would love to see this as well, but the devs probably don't want to develop something 1% (or less) of the community would play Starbase via.
will there be any reason for VR users to come to starbase if it did get a VR release?
There's a severe content drought for good VR games at the moment, so plenty of people would come and try out Starbase. However, the small size of the VR community would barely make a dent in the game's population.
Unless the game would be runnable on the Quest's successor well into the future (The Quest 5, 6 or even later). It wouldn't be worth the dev time, due to the small size of the VR community.
