(I was a systems engineer before retiring.) FWIW, I'd be interested to know where you found the 48/32 X 34/11 combination you describe. I've not seen that configuration for sale.
Where I'm located, there aren't a lot of long enough steep enough descents to make gears > 112 inches particularly useful for this very cautious downhill rider. Usable, certainly; useful to me, not so much.
He also left off that 12sp campy fits the older 10 and 11sp hubs so no need for different hubs.
