Unless you suddenly get sick and your HSM is unavailable?

Unless you get a 2nd person on the team (working remotely), and they want to be able to sign scripts as well?

You can still turn off the script signing requirement without running a script (right?). Presumably this will be logged to the Windows Event Log, so there should be a mechanism that watches logs for this and alerts someone to investigate.
