Absolutely, IMHO, because the cvs entry relative to the change that has
introduced the new client state, talks about refreshing the screen and
nothing else, and moreover, the relevant code that sends the disclosed
map to every client is in is place in the server.

from srv_main.c:


  send_game_state(&game.est_connections, CLIENT_GAME_OVER_STATE);


  notify_player(NULL, _("Game: The game is over..."));
  gamelog(GAMELOG_NORMAL, _("The game is over!"));
  if (game.save_nturns > 0) save_game_auto();

  while (server_state == GAME_OVER_STATE) {
    force_end_of_sniff = FALSE;

If you look at my "proof of concept" patch, you'll see that I've
modified only the code of the client, thus "cheating" can be done by
anyone with a little change of the code.

A good solution, IMHO, is that a client receive the whole map *ONLY* if
the game has ended (not if his game is over). I've not checked the code
and I'm not sure if this is the actual case or not.
