In my opinion, the reason why this question comes up so often is because the bubble itself ISNT static. Sure the models don’t always update, but flavor text, some areas, and even the placement of some NPCs absolutely DO update as you progress. And even if they don’t directly specify exactly how MUCH time has passed, the game does reference time enough for you to be actively conscious of it and curious. Time bubbles are fine, but if you are going to move me from one to another I’d like to know how much time has passed between them. I think that’s reasonable.

On the subject of updated models, I honestly haven’t seen a demand for SE to do that for NPCs. If anything, they take that initiative themselves with each expansion now.
