Some nix linters will remove unused arguments, causing context problems

[vic]

Also I think I will move to simpler direction contexts, instead of { fromUser, toHost } -> { userToHost } and we could access userToHost.user and userToHost.host (similarly a { hostToUser }).

This change would help in situations where you don't need to use both arguments, like my examples above, only use toHost and not fromUser, and I have to use # deadnix: skip so my nix linter knows it cannot remove the fromUser argument, because if it is removed the context will never match!, so I dont need formatters causing problems because of unused vars.
