Let us put Tank Transfer Valves in backpacks again

I agree with this. It's sorta shitty when a traitor is trying to bring his bomb someplace all stealthy and slips on a wet floor and gets mobbed when he drops the bomb in front of someone. Maybe it could take up a lot of space in a pack to where you can't put anything else in? Or there could be suitcases that hold them or something?
