I do not know if this is intentional or not, but vindicators will not attack you unless you attack them. Although it might be a glitch, I kinda like the idea of mansions being inhabited by villager-like creatures who are nice, but will defend their home if they have to. I prefer them being neutral, but if it is a glitch, I understand if you have to patch it. It would be nice if they would naturally attack evokers so that it is like the evokers are trying to take the mansion over, since they are still hostile. Then you could help them take back their home and in return you could live together with them. This would work since the only things you really need to make a mansion your home are some workbenches and a bed. Of course you would need lighting too, but that's a given. You might want to add doors too but there is a lot of creativity possible in that area. Also, we need Illusioners/Illusion_Illagers in bedrock. A cool idea would be to let them spawn in zombie villages to protect them, similar to iron golems in regular villages. Another, idea is to have evokers turn into them if struck by lightning. I think they are the coolest unused mob in java and I'd like them to at least be spawnable with commands in bedrock.
