I hate liver, no one in my family will eat it, therefore, it goes with the rest of the guts. The whole family loves heart, which is why I usually hold a little high on lung shots. Get the arteries, leave the heart intact.
Somewhere a line has to be drawn, the kidneys are edible, intestines for sausage casings, or a bow string, or cordage. Sinew for cordage. If cwd isn't a concern the brain is edible, or can be used to tan the hide. Bones for stock. I could go on, but I think the point has been made.
To get fined for waste of game, requires both an officer to write the ticket, a judge to agree, and if it comes to it, a jury to unanimously agree.
Just the rib cage doesn't have much meat, especially if a good job was done when removing the front legs. The neck has a decent amount of meat. The loins on the underside of the spine, near the pelvis, is some of the best meat on a deer/elk/pig. I see no easy way to get it with a gutles method.
