Well, I would think this will cause some problems with restraint
generation later on, because then you would need to check for every
pro-chiral if there is an assignment for the corresponding ones to
distinguish degeneracy from situations where you have different shifts
but no stereo-specific assignments.
Thus for structure determination its nice to have Hb* around.
