I think you're assigning too much weight to the word itself. In
informal settings, or even quasi-formal ones, it's not uncommon to use "designed" when we don't mean "literally designed".
The use of "design" in the context of the structure and capability of human bodies means precisely "literally designed" to many religious people, including many readers of HN.
So I don't think it's out of place for the GP to address this.
Thank you. This was exactly the point of my comment. While some readers interpret the word lightly, there are many who use it literally in the context of biology with a reference to creationism. There is no evidence for creationism
