Since this is something that a lot of people would really enjoy, maybe this is something that deserves to be included in a potential future 2.0 update. Like once there's plenty of dev time to work on it after the game is pretty much finished. Since it would be so time consuming to include.
From another perspective, it might be a good thing to decide upon early in development, as it might be easier structuring the majority of the game with such a mechanic in mind and already implemented, rather than going back and reworking existing content around a new mechanic. Depends on priorities I guess.
