The T2 Cat A switch seems like the familiar Eurocopter cockpit/box-office design policy - let the engineers, not the pilots, decide what goes where.
If they have the wit to put a wiper-sweep switch and an ILS go-around button where they are needed, why not do the same with the Cat A? I don't mind what they choose so long as the pilot's hands don't have to move away from their normal positions on the collective and cyclic.
Then perhaps they can start on all the other controls that need sorting... getting rid of switches in the roof would be an excellent beginning.
