Fortunately my little guy was only ever meant to be a pet, so genetics won't be an issue. I'm not sure I personally would ever breed known wobblers together. Even if it doesn't stop them from eating, I do worry if it's disorienting for him. Sometimes he wraps his tail around his neck when I hold him, and I wonder if it's to steady himself.
Still, comparing him to the videos I've seen, his wobble is quite mild.
