We were told what the Nullstone does: "disperse the very essence of even the most potent entity, obliterating it completely". I assume that comes with an additional note that it only works on summoned voidsent and not all kinds of entities, or that is far too dangerous a plot device to have loose – too easy a problem-solver, too dangerous a threat.

I don't believe it had anything to do with Diabolos absorbing Scathach, certainly not based on what that very plotline had told us it was for, even before the 6.X storyline made it clear that voidsent fight among themselves and consume each other to gain more power if given a chance. At most, if he was wielding the Nullstone at the time (I would have to rewatch the scene to confirm), maybe he broke her earthly form so he could absorb her soul.

In any case, yet again, we do not want to go obliterating Zeromus completely.
