Sure, but if the opponent does not cooperate, I will just have to keep
playing until there are no valid moves left. Then I pass; if I can win
the game if the opponent removes my dead stones, I can certainly also
win if the opponent does not.
So actually, I might avoid passing just when all the _opponent_'s dead
stones are removed from the board.

final_status_list has a clear definition and no exceptions for that
definition are stated in kgsGtp docs; in fact, it even strongly implies
that final_status_list should never be called after kgs-genmove_cleanup
starts being issued. Also, kgs-genmove_cleanup says simply "do not pass
until all dead stones are removed", not "play as if all stones on board
are alive". Under the second definition, modifying final_status_list
output might be sensible, but certainly not under the first one.
So, given how my first attempt to freely interpret the kgsGtp interface
ended up, I will rather opt for following the specs to the letter this
time around. (Also, perhaps I feel a little stubborn about this right
now. ;-)

I fully agree with that. Well, it doesn't...
