Normal & Lockdown cheese is a game design choice.
It simply has to be part of the game, they can fix it overnight as they already don’t allow you to do it for secure ops, they also used to allow you to bring spare face shields too but stopped that with a small patch.
So the best you can do is either abuse it yourself or reap the rewards of people choosing to bring excessive value into a raid.
That’s it. The devs either don’t care or don’t listen, or they do and it’s created that way on purpose.
