An interesting hypothesis. Maybe the deeper question is, does the virtual world really need to reflect the physical world in a very accurate way, or does it suffice to represent a subset of that? And then, how accurate does it have to be? Does it map 1:1 or are there indirections that would work well to convey meaningful information and trigger actions that make sense?

I guess many important clues get provided implicitly. For some reason you want to mute notifications for a while, so you do that, and your avatar reflects it, but it may not be necessary to truly be in headphones mode whenever you happen to be wearing headphones, or vice-versa.

Our goal is to simplify things and avoid artificial complexity wherever possible.

Did you consider that a tree list that people call "rooms" might be a sufficient subset already?
