People will pick traits they want, and I doubt any specific thing other than "doesn't have disorders" would be universal.

While I have reservations about the tech, leaving it in the hands of individuals seems massively preferable to government regulations on reproduction details. Especially if what you can control gets more precise. Even the worst individual eugenics fantasy has nothing on govt deciding that all children share particular traits and lack others.

It's also not clear to me where the difference between choosing offspring vs choosing a partner for offspring ever becomes something law should enforce...or even can, while allowing editing against disorders.
