Idea ideas on how to make the new experimental changes to villagers better

I agree that the concept of special books from certain is cool but not allowing max levels of those books is just a horrible idea. They also shouldn't put a limit on curing villagers or lock books to certain biomes. I don't even think the changes to the wandering trader were that good when the could add a lumber jack villager. If they really want a reason to have villagers of biomes the could make the cost of certain trades cheaper rather than removing all the best enchantments from villagers. Ex a swamp villager could always have mending for the last trade but it could be on average 10-15 emeralds cheaper while still being able to sell every other book. A new lumberjack villager could also have discounts on the type of wood found in that biome.
