As I suspected some want a locked bolt and many don't care. I only know one guy who lost a bolt and he did it going up a mountain side in one of Alaska's legendary alder patches. He discovered it was missing after about 4 hours of fighting through the alders. He had slung his rifle to keep both hands free. Fortunately his buddy still had a functioning rifle.
I know I have locked my bolt down on and empty chamber when pushing through the alders after having a bolt come open, but it stayed in the rifle.
