Safety? Robustness?

For example, by adding people to "adm" you can allow them to monitor
machines, but when something happens and they want to do things they'd
have to go through "sudo" or "su", thus adding a psychological barrier
so that they don't break things... That means they can watch the machine
just fine, but "rm -rf /" when doing that will have no effect. But they
still can do priviliged things if they feel the need to, after auth.
