Yes, that is a problem. You can only hope that such a user would have good pass phrase(s) on their key(s). Though I would expect the attacked to have more luck using the information in known_hosts to pick targets. If you only use "unlocked" keys for cron jobs, and then limit access on the remote system, you can keep the risk manageable. I can picture a cron job that does a backup to a remote machine, or a backup client that uses an ssh link to communicate to a backup server on a remote machine using "unlocked" keys.
Mine goes through a vpn. It's possible to, to play tricks with iptables: a connection to ssh from example.com gets redirected to port 22022 where there's another ssh running, or DNATted to another box.
