The comments have more information as to why this is done, but the basic idea is that finding an exported trait is actually a fairly difficult problem. The true answer lies in whether a trait is ever referenced from another exported method, and right now this kind of analysis doesn't exist, so the conservative answer of "yes" is always returned to answer whether a trait is exported.
