Actually getting this to be useful for Psi4 is not so easy, so I would not bother, but this poses the question why to even have this function in the first place at it might be pretty specific to QCEngine. On the other hand this allows us to add new properties to adcc and make them available to QCEngine without the need to modify code in that repo all the time, which is probably easier to maintain.
