Very true, and you can also configure the server (ie the other end)
to only permit that keyfile to be used to run a single command.
That's particularly nice.  You do have to tweak various ssh knobs to
ensure that it doesn't ask you any unxpected questions (in cron nobody
can hear you scream) such as

   @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
   @       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @
   @    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
   Are you sure you want to continue connecting (yes/no)?

(What I just did was warn you to expect the job to eventually when
the server's IP address or host key changed.)
