This is why Star Trek's hostility to genetic engineering is so incongruous. In most respects, ST has always been a franchise that's optimistic about the potential of technological progress, rather than giving into kneejerk Luddite fears. Okay, TOS had the same kneejerk paranoia toward artificial intelligence, but TNG corrected that. And really, DS9 critiqued the fear of genetic engineering even while it established it, because Bashir proved that the fears were unfounded.
Also the hostility to genetic engineering is based on what happened to humans on Earth in the past yet the restriction seems to apply to all Federation species. Talk about taking a hammer to crack a nut and I doubt other species will allow human policies to dictate what happens to their race. Makes the franchise even more Terrancentric than it needs to be for suspension of belief in this fictional society.
