Could be. I dunno.
It doesn't "feel" right, though, and it also seems problematic. I don't quite get the point of faulting out a deleted object at save time if that also requires the discarded property information to be restructured into a different form and kept anyway. I don't see how deleted objects' objectIDs can survive a save without compromising the integrity of objectID uniquing across multiple MOCs.
But I dunno.
