I don't know about making the game drag on, but it will make resource gathering and mine profits a more significant factor when building a city close to completion. Of course, if there are many cities on the map, there is always something to build, but in other cases, I find the idea useful. And, to prevent the game from dragging on, it might make sense to reduce the number of resources required to build creature dwellings along with these new features.
I agree with the author. Such a mod could exist, but it needs to be refined so that there is no imbalance.

That's also an option. The only question is how much should the demand for resources be increased?
Regarding mines, it's better not to make it once a month (that's clearly an exaggeration), but once every 3 days.
