If I understood Heiner's original points, I have not seen much in the way of arguments against them. I would fully appreciate every other tournament deciding not to have finals, but I would want to believe a World Champion title has meaning closer to what Heiner suggested, not just having the luckiest pairings and, as I have expressed concern with elsewhere, being the most exploitative of less-competitive opponents.
That leaves requiring the same decks in finals. But I don't like the implication that players would then need to trade between picking their deck to qualify (maximize exploiting less-competitive opponents) with picking their deck to win against equally-competitive opponents. The Title then becomes who did the best trade-off, which is certainly a worthy skill, but should not World Champion require more-purely the second of these?
That said, I also dislike the possibility of a hypothetical gimmick deck winning in finals just because it was tailor-made against the right 2-3 opponents. I doubt very much that any of the current contenting players would opt to take that route, but I'm speaking in principle.
This leads me to suggest that my concern about requiring the same decks might be mitigated if the threshold of top-4 qualifiers were eliminated in favor of, say, another 2 or 3 more Swiss rounds, perhaps allowing players to be paired a second time. (Aside: is the difference between 4th and 5th in prelims
really such a meaningful threshold for justifying a comeback allowed from 4th but not 5th?) I don't think this would help if there was a majority of players trying to exploit less-competitive opponents (the pairings would just tend to pair similar such opponents), but if those are a minority I would hope that these extra rounds (presumably against more equally-competitive opponents) would have the effect of diminishing the impact of random pairings.

It sounds like Chris is suggesting that to be a candidate for the World Champion title, one would need to attend two consecutive years' worth of tournaments. For purely selfish reasons, I would not want the title to require such regularity. That is what the meta-title of most-World-Champion-titles is for.
