Villagers should be less passive when faced with zombies and raids

Villagers within a village that has an armourer and weaponsmith should pathfind to them in the event of zombie or raid sightings, and equip themselves to fight back - this should contribute to the leveling of the villager but not "lock" in actual trades, simply leading to higher levels of gear being equipped by the villagers who stop there. The "ahh zombie, run" approach made sense once upon a time but who or what are the professions for if they never use them to defend themselves? You're telling me they just have traders on the off chance someone comes past? The villagers have upgraded but the village mechanics remain largely the same
