How does it work with with `~/.ssh/config`? Mainly, say I have keys in the vault for many machines, if they all get added to the 1password ssh-agent sock, won't you get "Too Many Auth failures", unless there is a way to pair the key to a `Host`? Maybe `~/.ssh/config` can pair keys to a `Host` by fingerprint instead of file?
tl;dr: you can pin public keys to hosts
