There are cases when a user might have multiple keys in ssh-agent,

You can do that with option "IdentityFile", see "man ssh_config".
That assumes that the key files are locally available.
If you are on host A and want to connect to B, it is perfectly
possible to have keys in the agent that were added on another host C.
Note you can provide to IdentityFile a file containing the *public* key.
So no need to copy the key into B.
(Actually, it can also be beneficial, as not having the key in the agent
will procude a failure, instead of ssh(1) requesting the key password,
which is an UI that could be produced by a compromised server)
