The areas where it would be important are on security/NOC systems, where there is almost unlimited power given the proper credentials.

The Runbooks that NOC teams have, quite often have them connecting to a lot of systems with greatly heightened privileges - It's not unusual for a NOC employee to have expansive sudo privileges on many of the unix hosts they manage. They are also often on privileged VLANs, with direct IP routing to a lot of hosts that normally wouldn't be reachable.

Most of our NOC guys have their own personal laptops, and they can hop onto the (unprivileged) wireless system and do their own thing when they aren't working an incident.

I'd have no problem having my screen captured once a minute when I was working in that type of environment.
