I was Campy's east coast service tech for a number of years. I routinely saw cassettes with spline damage from large loose cogs. Note that the damage was rarely severe, and I never saw one cut through. But I did see many where the sprockets were difficult to slide on or off over the raised burrs.

I don't know if the Shimano pattern would fare better or worse, and lack the experience data anyway. On one hand Shimano splines are shallower, but OTOH there are 6 vs. Campy's 4.

As I said, I wouldn't sweat loose sprockets up to 23 or so, but prefer carriers for the larger ones. Then, of course, it depends on where and how you ride.
