This data pack attempts to make villagers more of a necessity, rather than simply a convenience. To achieve this, several changes have been made:

• Several crafting recipes (for mostly later game items) have been removed such that villagers are now one of the easier sources of several items,
• The discount from curing zombie villagers expires after 4 days (just like it does on Bedrock edition),
• When a villager who has the curing discount gets zombified again, they lose their previous curing discount.

These changes motivate you to find and protect villagers. You're driven to invest in them, and they become more a part of the central gameplay of Minecraft, rather than being a side curiosity or exploitable cheap source of enchantment books etc. Some of the removed recipes are for items that occur as both trades and structure loot, so you can also acquire the items by exploring (and now that loot which was previously worthless has value too).

No villager trades have been changed; they all remain the same so you know what to expect from them.
