If we're using analogies, `unsafe` is like a "hard hat required" sign. There's nothing intrinsically different about the space inside or outside of it, other than that you can't be sure a brick isn't going to fall on your head once you cross over. So it's on you to wear a hard hat. And to not drop any bricks and trust other people to do their best not to drop any bricks.
You wouldn't call that an escape hatch.
