Woodland mansions were introduced in 1.12 and were the only source of totems, until 1.14 came, which introduced raids, with evokers a part of them. Now, woodland mansions are pretty much useless because players don't need to go there for totems. By adding an advancement that you can complete by visiting a woodland mansion, players would be incentivised to go there for that advancement. https://19216811.cam/ https://xender.vip/ https://testmyspeed.onl/
its called survival for a reason if they added stuff that would make it easier it would not be survival it would be some sorta modded survival ina way.
