I'm torn on that one Chessie. I can see the arguments, but just think how many great matches we'd have been deprived of. Two that immediately spring to mind are last year's RG final (would have been straight sets to Jannik), and AO 2022 (would have been Daniil in straight sets over Rafa).
I've also heard people suggest that only QF onwards should be best of 5, but any player reaching their first QF is going to be at a big disadvantage.
