Most of the Catholic theologians I've run into/read about/heard about are fairly pragmatic about this sort of thing (especially the nuns.) There's the law, and then there's what people do, and then there's what people can do better even if they don't meet God's standards.
As for Protestants, you'll find many who agree with the Catholics, many who agree with what you've called typical, and many who consider human life to begin at birth. But most people have a loose affiliation with their denomination, and I don't think there's much that can be called typical about the rank-and-file Protestants or Catholics for that matter.
