No base type location is currently planned. However, non-combat companions like a smith will get added eventually. They will probably not add passive combat bonuses though. If I recall correctly, one of the planned companions is the healer who’ll give your mercenaries a chance to survive the battle if they were brought to 0 hp and not decapitated or made undead.
Not sure what you mean exactly with the third, but it could be that it’s already part of their planned reputation system. They’ll also soon post a roadmap of their future future plans for the game, so they might have something on it too.
