Yes, but if you have to go via another PMC register then you may spill. Whereas it seemed that the type retrieval ops went direct to S and I registers, which may save spillage. (at a cost of more ops)
Well, 1 extra register is required which shouldn't be enough to worry about. Spillage is pretty rare with the number of registers we have so I doubt it will make a difference.
