This is potentially a bit of a call out to everyone else. It could be really interesting, what happens next - well, could be, if conditions weren't so fickle. Style of ascent too. Will anyone else following, eschew the knee pad? It will be an interesting situation, if the historic interpretation becomes "de rigueur".
I know all of this has been thrown about before, but the pad/sans pad debate seems more relevant, but still hanging. No right answer of course.
Despite the grade, I've got to say that I think this is surely significant, as much for the rarity and historic aspects. I'm probably stating the obvious.
Would have been great to see. Any more photos/video?
