It's not a good idea to have the fan chat zone under the control of the company when you think of possible censorship issues.
Also it's not very healthy to create a second job for their vtubers where they have to spend more time inside this world after spending time streaming.
I saw what happened to smaller indies doing a shared minecraft server for their fans when they went inside to "play" with them.
You don't want to experience the equivalent of seeing red superchats in something that's supposed to be a game, but isn't for them and carries even more risks of a making a mistake with more "real life" interactions.
The live streaming format or live event format is what works best.
How would you handle 10000 fans in a VR world interacting with 1 vtuber?
The best you can do is with something like an event where you watch and move your penlight.
Or you could use a form of prerecorded NPC character an add a bit of AI in it but that would be a risky thing to do because what makes them interesting is that they are real so you can't use another person or an AI to "extend" them.
We don't want to experience what happened to Kizuna AI again.
In that case creating something like an attraction parc around the event venue for fans to meet after an event could be a start.
But they already have social media for that so at best it would be an extension of it.
What could make the experience valuable is for fans who usually only meet during live events to have a place to exchange more like in real life through VR.
It's difficult to meet people like you outside of niche platforms, although that may be different for Hololive fans in Japan.
But I don't know what will revive the interest in VR for larger adoption.
