Well, yes.... but some breaches are from remote machines that may be
able to life the /etc/shadow file due to a vulnerability that isn't
fixed and if that's all they have, then they don't yet need more
direct access.  If they have /etc/shadow, then they can work on
off-line brute force.

I'm very surprised at the very low password strength / length
recommendations to say the least!
