Librarian rework ideas (23w31a)

I find the idea needing to place or find villagers in specific biomes for specific enchants to be an exhausting thought. I have been in worlds where the closest jungle was 15k blocks away. Can we move away from the kidnapping/relocating and start working with the villages more? (#PreventKidnapping)

I WANT to have one place to go to for enchants. That doesn't mean librarians can't scale better with game progression. I think there are ways to make librarians less OP while adding to the immersion of spending time in a village of people. Here are some ideas:

• A librarian learns random enchants as they upgrade. They request items from the player to research (upgrade) the book to the next level. (Librarian quests)
• Working with the idea that master librarians have higher enchants: You give a librarian a magical item that rotates their inventory the next day.... could be: enchanted emerald
  - Requires player xp
  - Full enchanting setup
  - Maxed out librarians
• A village needs to be exposed to new things to be able to offer specific enchantments.  Examples of exposure:
  - diamond armor on an armor stand in the village boundaries: librarians can now learn protection enchants. 
  - obsidian = unbreaking
  - blast protection = Armorer in the village
  - silk touch = loom or bees
  - Efficiency = village has X population 
• Maybe the village has to trust you more before they offer you specific types of enchants?
• Maybe the books we find or enchant can be used to help librarians learn new enchants?
