By a "non-binding eugenics guideline" I mean something akin to "ex-convicts should not produce" or something, I mean there is absolutely zero state or national guideline that I know of that invokes arguments of eugenics, if you know of one then I am mistaken.
EDIT: I may have misunderstood you, I interpreted your comment to be about the hypothetical scenario where most people have genetically modified themselves into being "super heroes" and now the people who haven't can't keep up with the rest of society, so it becomes a practical necessity without being legally required. On second reading though I'm not sure if that's what you meant.
It turns out, as a society we haven't done that already, and neither has any other society. Conceptually, it's interesting to think an adult could have their genetics changed, but we have cheaper ways and we haven't even exploited those.
For the other things, the best editing technique in the world is useless without a known and well-defined target. Intelligence is certainly partly heritable, but it’s not like there’s a single switch that needs to be toggled: genome-wide association studies find hundreds or thousands of linked genes—-and many of them likely have multiple functions. I would bet over-expressing any single one of them leads to many, many more problems than it solves.
