I definitely wouldn't want resources taken away from the development of other aspects of the game, so I voted no. However, if there was an option included (and it didn't impact at all on my single player game), I could get my little sister into playing RPGs, which could be fun
But I just don't like the idea of another aspect of the game being left out/underdeveloped for something which - for me anyway - would be little more than a novelty which I wouldn't really use that often.
