Villagers ultra upgrade

I think if Mojave can get the programming down on the AI of villagers to where not only they should be able to defend themselves against pillagers and other evil mobs with visible swords, bows, and other useful tools such as axes for chopping trees themselves, shovels for landscaping to decorate town and add more buildings and paths, hoes so they can add farmland themselves and maybe plant anything other then potatoes, following that they should be able to hunt animals on there own and actually have visible food in their hands and eat it, now to the main thing i want is construction villagers who will build new houses and buildings as more villagers and golems spawn throughout the towns, please i just really want upgraded villagers they could be amazing
