>I don't think the climbing/ scrambling will prove tricky
In my experience (not that much, only done it once), the climbing will not prove tricky, but the scrambling might, especially if you don't pick the easiest line, which will almost certainly happen regularly, and/or pull off a hold at some unexpected moment, which certainly happened to me a couple of times.
I can't imagine why anybody takes ropes on this. You'll be in a position a hundred times in the day where a fall would be fatal; I really don't see that roping up for a pitch or two of V Diff is going to reduce the odds much, specially when these bits are so well-travelled and hence the loose stuff is gone.
While there's a load of scrambling, I still maintain that in distance terms, and probably also chronological terms, the large majority of the day is walking.
