I used to feel that way, but the body doesn't really come into play with a truss rod adjustment. If it makes you feel better, if you put an index finger on the headstock and push the neck into position prior to turning the nut, it removes most all of the risk (well, except for the truss rod itself snapping). On an acoustic, that takes one person holding the body and the other moving the headstock and making the adjustment because of the nut location inside the soundhole. But on an electric, put it on the floor, put a knee on the body below the bridge, use your weak hand to push down lightly on the headstock, and adjust the truss rod nut at the headstock from right to left as you're looking on it. If you're loosening the TR, you don't need to worry so much.
Now, you probably know all this, so I'll just change the subject. What with the rotary dial phone, man? Are those things even legal? I'd love to see a teenager try to use it.
