What you're describing is clearly eugenics, just a benign form.

Benign eugenics? I can't follow...

It's common for people to choose to try to not have a child with a serious genetic disorder.

tfw a connotation is more powerful than a definition

Carrier screening covers a really small fraction of pathogenic variants. It'll catch really catastrophic stuff but there's an enormous number of mixed-penetrance/AD variants that people pass on because they aren't lethal.

(plus, let's be real, most prospective parents don't carrier screen. only ones about to undergo IVF where PGT-M is sometimes an option.)
