[Precarious]

Back when charts were rated 1-99, vrofl was rated 999, which is obviously an even greater exaggeration than 255 on a 1-120 system. But it's only an exaggeration because of how the system scales, and scaling past 120 is essentially meaningless when files of that nature clash with the intended player meta of FFR.

As I understand it, a 120 file should be just barely DDGable for the absolute top players, and vrofl is simply not DDGable by a human. Since its difficulty is so high that it doesn't really test one's ability to approach an AAA, even rating it correctly distorts the "purpose" of the AAA equivalency. Since it's structurally outside FFR's intended purpose, the 255 (and the prior 999) feel appropriate to me.
