Yes, this would definitely be a "nice to have" feature, but I am much more interested in a quicker to market product that we can start using now. Is that an enhancement we could add later?
It seems like it would add a lot of complexity to the code, and perhaps even to the day to day self-management. But it's true we often have people on 2+ projects or filling 2+ roles. Without that option the board would not be completely accurate. Maybe that would give us visibility to a practice that we acknowledge isn't the best.
