we want to raise villager unemployment
ex pylonmc/pylon-base#434 fixes using the block, but they can still get the farmer job from it
likely needs a listener on VillagerCareerChangeEvent with https://jd.papermc.io/paper/1.21.10/org/bukkit/entity/memory/MemoryKey.html#JOB_SITE to check which block it is, then cancel evt if its a pylon block. Maybe this should be a core iface, or do we just implement this as a blanket restriction on pylon base blocks?
