If it's the same key that provides access to all machines, of if the
key() are unprotected by passphrases (or something), then that is a
weakness. Whether it's acceptable in your situation is your call, but it
is a weakness.

I'm hoping you're not serious :-)

If systems have nothing of importance on them, they don't need
protecting. If, however, they have *access* to something important, then
they need protecting at least as much as the important thing, because
they can be a bridgehead.
