Agility benefits nations wanting to crack something, because they can force you to pick an insecure combination. This has happened in the real world several times before.
And what they will get is "haha! It was only 230 hours and we cracked their ... oh, there's another dozen sparse files inside that and it's a different combo..." I can automate encrypted sparse files all the way down each showing a size between 5PB and 40PB which a lot of forensic software will try to copy as a non sparse file.
