There's one issue & I know it seems absolutely trivial but I guarantee that there'd be a HUGE outcry by certain parts of the community. That issue is longevity. If they move houses they'll want to keep the existing comments. Worse still, they'll want them to be permanently stored & should the game last for, say ten years (!) that could be an immense amount of data that really has zero use but has to be maintained & kept error free.
