Part of the problem is that in builtin/pack-objects.c, we have the 
following:

         if (progress)
                 progress_state = start_progress(_("Enumerating 
objects"), 0);
         if (!use_internal_rev_list)
                 read_object_list_from_stdin();
         else {
                 get_object_list(rp.argc, rp.argv);
                 argv_array_clear(&rp);
         }
         cleanup_preferred_base();
         if (include_tag && nr_result)
                 for_each_ref(add_ref_tag, NULL);
         stop_progress(&progress_state);

and the logic for walking uninteresting objects is the 
mark_edges_uninteresting() inside get_object_list() (both entirely 
contained in this progress state). Perhaps the best thing to do is to 
untangle the progress for the two modes based on 
'use_internal_rev_list'. Could we then have the progress for 
get_object_list() be "Walking objects" instead?
