So on a 35 degree slope, you wouldn't want to see people making controlled short radius turns? You would prefer to see people ripping carved turns at 40-50mph? Above you suggest that if everyone skied "properly" we wouldn't see bumps. How do you define skiing "properly" The only skiing that won't form bumps is straight down the fall line. If you are skiing in control, you are pushing against the snow. Pushing against the snow moves the snow into piles.
I would say that if everyone skied properly, there would be bumps everywhere, and very little complaining about it.
He said "more" carved. If you make turns 8-12 meter long and about 3-5 meters wide you can get down safely on any groomed trail and they are either carved or close to. They would make some pretty massive moguls though. Incidentally, that is pretty much like an SL course and IMO it is a good target turn size.
