In addition to the editorial reasons these were originally separated, there were some legitimate technical reasons why these needed to be separate abilities. While those technical reasons have since been eliminated, the fact that these were working fine means they just never got revised. I, too, see no reason there can't be an additional listing for the Innate Attack advantage that uses choice lists to set the type of attack; this just never got done because it never got thought of or suggested after the technical limitations went away.
