Teams can't afford to do that now.
No team could afford to do that even during Ferrari's heyday.
MSc would definitely get first pick. He is No.1. There is no question that this was the case. However, to have newer parts available and not offer them to the No.2 driver, is quite bizarre.
Can you give me an explanation of why a team would do this (Ferrari or any other)...I genuinely would like to know?
