In principle, I would be all for playing without obelisks, healing forts, cartographers, water artifacts; I would also add water spells myself, if they are either not used or have no place to be used. The question is - how will the community react to this? And creating a mod if desired is not that difficult, but it takes time.
I would suggest creating a thread to discuss such features. If there are more such posts, because, in my opinion, they are not directly related to the HD mod.
P.S. Everything is feasible, if there is a desire and time.
If you want to play a different version of the game, go to WT, and it will essentially be your right...
