More than just cooperation, if I understand correctly what you describe it would also require some sort of centralised database with the info on who is “maintaining” which resouce .. good luck organising that =P
Also, if a thing like that affordances list (or maybe even a smaller one, like story progression) has only 10 attributes one may want to change (or not change), that already results in 99 possible combinations (even with just boolean changes). I am not sure who would consider it fun to update 99 different flavours of a mod on every patch ..
Did TS3 also have tuning for every single object? (I really don’t remember)
