I can't see what crafting or resource collection would actually add to the game. Between delves and catalouge there's already an essentially unlimited supply of food items, and that's if you don't want to use the brothel which really is an infinite resource farm since it takes less food and water to get through a day in the brothel than you can buy as a result.
Can't say I agree with the complaints about psionic either, I didn't feel that it was meant to be your primary tool unless you take the occultist background, in which case you have plenty of focus to spare. Keeping a backup simple melee or ranged option for any moments where you do need to rebuild your focus is part of the strategy of it.
