These little privacy leaks are not important on their own. A little data leaks here, a little there.
What is concerning is that we can guarantee private investigators and professional identity fraudsters are well on top of all these little loopholes. And combined, I'd say Facebook is probably pissing data out.
Some sweet law enforcement potential here - slap in a request to Facebook on a drug-dealing suspect, find a list of everyone with his number in their phone. Repeat until !exists($drugNetwork).
