You have to beat a big side or two at some point to win the World Cup. It doesn't matter whether you do it in the quarters, semis, or in the final.
At the end of the day, the final will most likely contain New Zealand, who've won it three times, and whoever out of South Africa/France who gets there will have to get past England, who've won it once and were beaten finalists in 2019. It's not like the entire competition will be devalued by this being the quarter. No one will say, 'Ah, France won it in 2023, but they only beat England in the semis, when it should have been Ireland - who've never even been in a semi before, and are serial bottlers'.
The rules are pretty clear and personally having a quarter that isn't a cake walk makes the competition more interesting, does it not?
What has sucked a good deal of excitement out of the World Cup is not the organisers but how bad Australia have been.
