Yup, that was the first thing that came to my mind, i.e. the code that installs a new packfile on disk in our repository must be ours, so we should be able to tell that code to add the new packfile to the in-core list without having to scan. We may still need to scan when that strategy "fails" to protect against racing with simultaneous repacking, though.
