This is admittedly a bit of a movie plot threat, but could an evil maid attack rewire this, then later malware takes advantage of the rewiring? IMHO layers of security are good. On my end I worry about the risks of constantly just leaving my Mac, which has filevault enabled, simply protected by a screensaver. Is that less secure than if I put it to sleep? And presumably turning it off completely is safest? How do I make informed choices about how much "locking" to do when I step away? These are all things I think about reading an article like this, and I'd love to hear other's thoughts.
