Control on Villagers Professions

I think professions for Villagers should be more controlled, like if they cant access the block that makes the profession they shouldn't be able to take on that profession. For example, if i put a villager in a fence and place a smoker outside the fence, they should not be able to become a butcher. Or if a Blast furnace is on the other side of the wall and there is no possible way for the villager to get to the blast furnace, they should not be able to become a armorer. I would love to see this added because i have built a replica, compacted area of villager houses for a survival world and i want to build my house near it but the villagers keep taking professions from inside my home and they want to enter my home, and that in my opinion is annoying.
