Whoops. On further thought, this is of course not quite true. In triple ko, for instance, one player will capture the opponent's group. The correct thing to say is that playing out a cycle will (most probably) never be better than not doing so.

No result has been applied in real life many times. My favorite was a tv championship that ended that way. The players got a short break, change of officials and tv commentator, and they restarted the game.

That was easy...

For longer games, you can decide if you want ties or if you want a rescheduled match. Saying it's impractical is a bit silly.
I had once a dispute where my opponent took back his move and placed it on another intersection. There were no witnesses. The referee decided that must start a new game with the remaining time on our clocks. I had 6 minutes left and my opponent 9 minutes and we had 20 sec byoyomi. I won by half a point.

How would you have a takeback? For triple ko, you can call over the ref and continue from the current spot unless you disagree about where the very last move was.

The takeback was not in ko fight. My point was that the new game, which could also occur after no result, was played with the remaining time in the clock, thus it did not create any problem with the schedule.

Sure, my preference is to handle it with a tie. Replays generally happen in professional tournaments with big money. In amateur events, I'd call it a tie and move on.

It is fine to have a tie, if it does not destroy the tournament system.
