Lets talk bout Biome based liberarians

Personally i hate this idea it will make MC alot more tedious for no reason and as a person who enjoys the game after getting maxed gear and building giant farms and stuff this will be a huge turnoff. So here my idea to balance villagers. Instead of giving them biome specific trades u could add 3-5 achievements for every villager job type (liberarian,farmer,blacksmith,etc) which have to be completed in order for you to trade with the villager job type. These achievements would increase the time taken to set up maxed halls while also not being extremely boring and tedious to do. The achievements could be biome specific which would increase exploration aswell. Maybe one or 2 could be like find a swamp villager or something. Once all the achievements are completed u can trade with the villager job type all you want.
(in this update the trades would be same as they are now)
