I have 27 villages in the village but only 3 iron golems spawn in. I feel like the iron golem balance is not too great on this snapshot, I believe that it should revert to the orginal spawn rate for iron golem but with fixes such as, if trade alot with villagers, iron golems will keep increasing in spawning one per day. The less you trade with villagers, the more danger the village will be in. Also, In this pre-release, when go to a new village, they don't get iron golem naturally spawned  in the village. Which is bad.
