Interesting, but is there ever an assumption that these sessions are
"secured" from the superuser in Unix in the first place?

- root has direct access to memory to retrieve session keying material
- root can read the shadow password file
- root can trojan/patch sshd to collect credentials and session data
- root can read/write the pty
- ...

Seems like fearing root on a (local or remote) system you're logging
into is a little redundant.
