A triple ko is not a tie, it is a no result. It is as if the game was never played.

The problem with a rule saying that a game must be replayed is that it is just impossible to follow in practice.

Tournaments organizers already have a hard time starting the rounds in time. Now imagine all the players waiting for the last round of the tournament to begin, with a delay of 20 minutes, some wondering if they'll be able to get their train because of the delay, and suddenly, an announcement is made that the next round is delayed 3 more hours to allow one game to be replayed

Such a rule is never implemented under such conditions. But for pro tournaments, with a delay between rounds, it is practical.

Simple solution: Do not reset the clock.

Just clear the board and restart the game. This means the players may be in byoyomi immediately, if the triple ko occurs late in the game. This will probably add a little time to the round, as the players may play more byoyomi periods, but not 3 hours.

Effectively, with this rule, the players have to get a result within the time limits given for the game, even if it restarts.

How would that mesh with time limit requirements for rated games? Particularly if one player is in byo-yomi with one or two periods left and the other starts the game with 10 or 15 minutes (or more) on the clock? If there was an unresolved triple ko, it's because neither player thought they could win after losing it. They should be considered equally responsible for that result, and the resolution shouldn't give bias to one player or another.

As an aside, I have no problem with treating triple-ko and other void games as a bye for each player for that round, and just moving on.

It doesn't. My proposed solution is meant only for situations where a tie or other solution (such as a bye for both) is unacceptable, and there is no time to replay with new full thinking time. For example: if the players are still in the running for a indivisible prize (e.g qualifying for the WAGC) and a winner is required (e.g. it's knock-out) and this is not the last round.

Has there ever been a superko battle in a professional game? Sensei's Library says Chinese rules allow superko, is this true? Has it ever happened?

According to Zhao Baolong 2p China, see http://home.snafu.de/jasiek/c2002com.pdf under Comments for Forbidden Repetition, in 100% of all professional Chinese tournaments, it is a tie. If you have different information, please state your sources and references! Rumours are not helpful.
