Yes, but evolution is stupid, so our sexual instincts are not very well-aimed. Rather, like much else of cognition, they are a bunch of hacks thrown together, which then require arbitrary patches like a cuteness response to solve problems like parental care. (Compare: if our decisionmaking were perfect, we should have accurate agency detection rather than hyperactive agency detection; if we could control our nonverbals well enough, we should have accurate rather than inflated estimates of our own attractiveness.)
But that wouldn’t work as well. I, as a human, would like to be that way; it would still reduce my genetic fitness.
