Well, this is actually a good thing given Facebook's mission, "Making the world more open and connected."
To do this, you have to have public profiles. Do you want your personal email to show up on public profiles? But Facebook email, on the other hand, probably doesn't matter (at least not right now when the "open" paradigm is still in infancy.). Its OK to be shown to random people and search engines and other features that come down the pipeline.
