[2021] What if... Villagers didn't always agree to join you?

Has Midjiwan looked into occasionally hostile villages, something slightly like the barbarians from the Civilization series, where there is a chance that trying to claim a village actually created a neutral unit that pushes your unit off and either fortifies within the village or attacks any non-neutral unit in unclaimed territory?

It could be tied to difficulty, maybe the first 3 villages still guaranteed to join you, and the unit tied to either the claimant's tech levels or the most powerful tech level on the square. Just a thought, and I'd like to know if this has been considered.
