@Patrick

Backdoor #1: Ctrl-Alt-Backspace .

@Patrick

Backdoor #2: Ctrl-Alt-F1 , Ctrl-Alt-F2 , etc.

This is now mentioned in documentation:
Protection Against Physical Attacks: Difference between revisions - Whonix

Backdoor #2: Ctrl-Alt-F1 , Ctrl-Alt-F2 , etc.

These keystrokes will switch to a different virtual console, while leaving the console that X11 is running on locked. If you left a shell logged in on another virtual console, it is unprotected. So don’t leave yourself logged in on other consoles. You can disable VT switching globally and permanently by setting DontVTSwitch in your xorg.conf, but that might make your system harder to use.

Should we set DontVTSwitch in xorg configuration by default?

And/or Auto Logout Virtual Console on Inactivity?
