og_menu calling nonexistant / redundant function

In og_menu there is a call to og_list_groups_page but that function does not exist anymore... also the path 'og' is handled by the view 'og/all'

My guess is that that following menu entry for 'og' may be safely removed

function og_menu($may_cache) {
  // cut out some lines
  if ($may_cache) {
    // cut out some more lines
    $items[] = array('path' => 'og', 'callback' => 'og_list_groups_page', 'title' => t('Groups'), 'weight' => 3, 'access' => user_access('access content'));

I didn't make a patch for this because I have no idea how to properly test if the removal of this line has side effects
