You seem to think that this would be a security advantage,
but it can act quite to the contrary when people's passwords
are printed out (with small, usually readily identifiable, typos).

In fact, many systems DO log "Bad Login Attempts", but they should
do this only into a secure file, not to the console.

Gould UTX-32S was rated C1.
UNIX System V/MLS is rated B2, I believe.
I think there are other NTSC-rated flavors of UNIX.
