I can see that. Seems that in the Pleistocene, the GM ignoring a die roll or considering it to be one higher or lower or whatever would have been seen as cheating, because he would have been expected to be working against the players'/characters' interests; here in the Holocene, though, it might be more a matter of taste regarding whether the GM is expected to have a story in mind, or maybe even just a desire for any PC deaths to be relatively meaningful.
Interesting that a
player doing any of that will probably still be considered to be cheating.
