We're talking about embryos here. I think you're well aware about the ongoing discussions on when those are to be considered humans and when not. That's not an easy topic, obviously, but I'm fairly confident that we won't throw babys in the garbage can if we don't like them but try to make those decisions as early as possible.

Why not? What exactly is the limiting criterion? Sentience is the main criterion that people who want to argue for animal rights and yet support abortion use, and it's a pretty squishy criterion. Already Peter Singer supports veganism and effective altruism (i.e., rebranded utilitarianism), and yet is perfectly okay with both abortion and infanticide, at least until the child gets "sentience".
