That's an extreme (because it makes it obvious) example — but the point is more broadly applicable. Leaving that one out attracts a more diverse set of applicants, like your fellow engineers, and more women. If you go the rock star route, you attract a very narrow band of person. There's even more subtle phrasing in developer job postings that attracts men and discourages women, though. Even something as benign as "quarterly company retreats in the mountains" might discourage parents, probably women more than men.
