In your circumstances, depending on the security of the key you're using,
yes. But I'll note from the very first you are are still protecting
against the same thing my change is protecting against: you can't get
root on that box with just the root password.
However, it seems to me that the other attack you posit (a trojan for su)
is still open: just gain access to your machine and trojan ssh.
